* altos: Wait after configuring boot pin before testing itKeith Packard2013-05-07
| | | | | | | | Clearly the pin isn't quite ready just after it's been configured, so hang around for a while (100 nops) to let things setting down before testing the value of the pin. Makes booting a lot more reliable. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Create per-product flash loadersKeith Packard2013-05-07
| | | | | | | Split the flash loader prototype into pieces so that each product can build a custom flash loader with very little code. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add ao_boot_chain to telemega v0.3Keith Packard2013-05-07
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Remove stdio from stm-flashKeith Packard2013-05-07
| | | | | | This saves enough memory to fit in under 4kB Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Get rodata into flash, make sure sections are alignedKeith Packard2013-05-07
| | | | | | | | .rodata* needs to be in flash; otherwise strings get left in ram. Failing to align sections makes the initialized data get dumped into the wrong place in memory. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make stm-bringup build againKeith Packard2013-05-07
| | | | | | stm requires AO_BOOT_LOADER_BASE now Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Run self loader when application sets boot addr to 0Keith Packard2013-05-07
| | | | | | | This causes the flash loader startup code to fall into the loader when the application sets the boot address to zero. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Allow STM usb driver to be used without stdioKeith Packard2013-05-07
| | | | | | | This lets the self flashing loader be linked without any of the stdio code, which saves a bunch of memory. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm-flash: Check target flash address against AO_BOOT_APPLICATION_BASEKeith Packard2013-05-07
| | | | | | Allows that value to change Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Use flash loader on all STM productsKeith Packard2013-05-07
| | | | | | Includes the boot chain stuff Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Provide another 4kB of flash space for appsKeith Packard2013-05-07
| | | | | | With the flash loader now < 4kB, we can use the spare 4kB for applications Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Shrink stm flash loader to < 4kBKeith Packard2013-05-07
| | | | | | Saves 4kB of flash space for applications. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Allow core timer to be excluded from buildKeith Packard2013-05-07
| | | | | | | This removes all of the support for the base 100Hz timer from the system, saving space when not needed Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Don't define task macros when not taskingKeith Packard2013-05-07
| | | | | | The necessary data structures aren't defined in this case. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Eliminate stdio looping when system has a single stdio sourceKeith Packard2013-05-07
| | | | | | No need to loop if there's only one Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Move ao_notask to coreKeith Packard2013-05-07
| | | | | | | The STM flash loader wants to be taskless too, share this very simple implementation of sleep/wakeup. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Add comments to the .ld files explaining how the romconfig stuff ↵Keith Packard2013-05-07
| | | | | | | | | | | works Would be nice to be able to explicitly define addresses for the romconfig variables, but I can't figure out how to make that work. Instead, just explicitly load the files in teh right order to make things land in the right places. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Add .elf to .ihx ruleKeith Packard2013-05-07
| | | | | | Uses objcopy -O ihex to extract the initialized bits from an elf file Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Switch ao_stm_flash to read/write binary blocksKeith Packard2013-05-07
| | | | | | | Change from development testing code to something that actually reads and writes data from the USB link. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Create ihx version of stm-demoKeith Packard2013-05-07
| | | | | | Both ao-stmload and the eventual java loader will support ihx files. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add erase command to stm-flash app. Validate addresses.Keith Packard2013-05-07
| | | | | | | | This also leaves the code writing fixed values and printing read data in ascii instead of binary. Useful for debugging, will want changing for the product. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Fix STM flash programmingKeith Packard2013-05-07
| | | | | | | | | | | Wait for flash to go non-busy after writing or erasing a page and before jumping back out of the RAM code. Export a separate 'erase' operation for testing. Re-lock flash after every operation. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Validate boot chain start addressKeith Packard2013-05-07
| | | | | | | | | | If the first block of boot memory has been smashed, and the start address is bogus, don't bother trying to jump to the application. This makes the system more resiliant to flash failures, presuming the loader erases the first block, programs the other blocks and then finally comes back to program the first block. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Mark .boot section as (NOLOAD)Keith Packard2013-05-07
| | | | | | | | | For some reason, the silly linker marks things in section .boot as data rather than bss, so they'd end up initialized by default. Force them to be NOLOAD so they preserve values across reboot so that boot chaining works properly. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Fix up stm-flash output file name. Use discovery LED pinsKeith Packard2013-05-07
| | | | | | | | | | Include the AltOS version in the file name, just like any other AltOS program. Switch the LEDs to the discovery board as we're using that. Eventually, we'll stop using LEDs entirely. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add actual flashing functions to stm-flash appKeith Packard2013-05-07
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Clean up boot loader supportKeith Packard2013-05-07
| | | | | | | Split out code into separate files. Add support for getting back to boot loader from application. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add program flash functionKeith Packard2013-05-07
| | | | | | | | And get it loaded to RAM so it can execute correctly. Nothing calls it yet... Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make stm-flash capable of switching to applicationKeith Packard2013-05-07
| | | | | | | This shrinks the base OS load down a bit as well so that stm-flash fits comfortably in the first 8kB of memory. Signed-off-by: Keith Packard <keithp@keithp.com>
* Add STM self-flashing loaderKeith Packard2013-05-07
| | | | | | | This allows the real application to get loaded at 0x2000 and jumps to that at startup time if the boot pin is set appropriately Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Sanity check barometer before going to pad modeKeith Packard2013-05-07
| | | | | | | Make sure the barometer is reporting some sensible value before letting TM try to fly the rocket. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Elide M25 debug output from storage info commandKeith Packard2013-05-07
| | | | | | | This is just chip-specific info that no UI actually needs. It takes a bunch of ROM to write it though, making TeleMetrum not have much space left. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Set APRS deviation to 3kHzKeith Packard2013-05-07
| | | | | | | | I finally found a bunch of references to APRS on the net and they all appear to assume a 3kHz deviation. Let's see if this works better with Yaesu radios. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/test: Fix warning in ao_aprs_testKeith Packard2013-05-07
| | | | | | Was not forward-declaring ao_radio_send_aprs, causing a warning Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Use SYSTICK on STM32LKeith Packard2013-05-07
| | | | | | | It's probably more power efficient than using one of the timers, and it's certainly easier to configure. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Mark GPS telemetry packets with GPS time stampKeith Packard2013-05-07
| | | | | | | | This provides a reasonable accurate indication of the system time when the GPS location data was received, and also makes sure GPS packets get some timestamp when no other telemetry is being transmitted. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Use separate exception stack on STM32LKeith Packard2013-05-07
| | | | | | | | This reserves 512 bytes of memory for a stack, then makes sure that exceptions continue to use that stack while processes use the per-task stack. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Reduce stack usage of FAT driver and loggerKeith Packard2013-05-07
| | | | | | | | Move some large stack arrays to static storage. Also eliminates some printf error messages which don't seem that useful except for debugging. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Open up the DVGA gain to use all of the available settingsKeith Packard2013-05-07
| | | | | | | We usually work in RF quiet areas; let the AGC hardware try all of the available gain settings. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Stop using telelco v0.2 top LEDS for radio TX/RXKeith Packard2013-05-07
| | | | | | | The top LEDs are now used for signal strength; a red LED indicates failed communcations, so we don't need to blink stuff and annoy the user. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make cc1120 driver return false on recv timeoutKeith Packard2013-05-07
| | | | | | Was returning an uninitialized value, which was often not zero Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Reconfigure CC1120 receiver to match our usageKeith Packard2013-05-07
| | | | | | | Open up the AGC to the full range. Set the AGC ref based on our receive BW (100kHz). Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Compute "real" RSSI value in radio code as neededKeith Packard2013-05-07
| | | | | | | | | Instead of dragging around the weird CC1111 RSSI values, just compute a dBm value in a signed 8-bit integer, ao_radio_rssi. Use that everywhere we need RSSI internally. We leave the weird CC1111 value in the packet reply as that's what the host expects. Signed-off-by: Keith Packard <keithp@keithp.com>
