* altos: Wait after configuring boot pin before testing itKeith Packard2013-04-28
| | | | | | | | 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: Clear any broken cc1120 TX fifo bits before transmittingKeith Packard2013-04-28
| | | | | | | | This just goes and clears the transmitter before using it, just in case it got wedged somehow. It also clears the bits while waiting for the radio to go idle, otherwise it'd never make it. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Make cc1120 driver wait for TX finishedKeith Packard2013-04-28
| | | | | | | | | | Otherwise, we may come in and try to use the radio again too quickly, causing it to go into a TX fifo error state. This change watches the MARC status until the transmitter is explicitly marked as finished. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Provide timeout value to ao_radio_recvKeith Packard2013-04-28
| | | | | | | | | Instead of using ao_alarm around calls to ao_radio_recv, provide an explicit timeout value as needed by radio functions with more complicated system interaction than the cc1111. The timeout is 8 bits of clock ticks. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Build test framework for AES codeKeith Packard2013-04-28

| * altos: Make SD card driver compile without radio supportKeith Packard2013-04-25
| | | | | | | | | | | | | | | | The SD card driver blocks the radio when trying to access the card as that operation appears very sensitive to RFI. This fix makes the driver work when there *isn't* a radio driver in the same device. Signed-off-by: Keith Packard <keithp@keithp.com>
* | altos: Remove stdio from stm-flashKeith Packard2013-04-27
| | | | | | | | | | | | 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 Packard2013-04-27
| | | | | | | | | | | | | | | | .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: Run self loader when application sets boot addr to 0Keith Packard2013-04-27
| | | | | | | | | | | | | | 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 Packard2013-04-27
| | | | | | | | | | | | | | 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: Allow core timer to be excluded from buildKeith Packard2013-04-22

| * altos: Delay while waking up SD card a bitKeith Packard2013-04-12
| | | | | | | | | | | | | | | | This seems to make bringing the card from idle to ready mode more reliable. If you spam the card with requests, it will eventually whinge and shut down communications. Signed-off-by: Keith Packard <keithp@keithp.com>
| * altoslib/altosui: Carry receiver status around in AltosListenerStateKeith Packard2013-04-09
| | | | | | | | | | | | | | | | | | | | This moves the crc_errors into the new structure and adds a receiver battery voltage value there as well. Now the receiver status can be monitored separately from the flight status. That also means that code receiving state updates should be prepared to accept missing listener or flight state values.

| | | | | | | | | | | | | | | | Trying to get the radio to stop modulating the carrier when calibrating the radio, we'll try RDF mode which says no preamble or sync data. This might shift the frequency though? Signed-off-by: Keith Packard <keithp@keithp.com>

| * altos: Horrible kludge -- disable radio while talking with SD cardKeith Packard2013-04-01
| | | | | | | | | | | | | | The SD card really doesn't like the RFI generated by our enormous radio, so just lock the radio out while working with the card. Signed-off-by: Keith Packard <keithp@keithp.com>

| * altos: Retry SD card I/O. Use time for timeouts instead of countsKeith Packard2013-04-01
| | | | | | | | | | | | | | | | | | | | Sometimes I/O operations may fail; give the card a chance and retry the operation in case it works the next time. Replace the loop counts with loops that check the clock so that they'll have consistent timeouts even if the CPU or SPI speed changes. Signed-off-by: Keith Packard <keithp@keithp.com>
