altos: Add EXTI_PIN_NOCONFIGURE to exti interface, use for MS5607

2013-05-20T03:04:29+00:00

This asks the EXTI code to not mess with the pin configuration so that the MS5607 driver can get interrupts on the MISO pin while still using it for SPI. Signed-off-by: Keith Packard

altos: Move ao_data.c from stm to core

2013-05-18T09:52:49+00:00

This should be used on every processor Signed-off-by: Keith Packard

altos: Grab SPI mutex until MPU6000 I2C mode is disabled

2013-05-16T05:13:08+00:00

If other drivers use the SPI bus, the MPU6000 gets confused as its sitting on the bus looking for I2C messages. Just grab the mutex before the OS is running and hold onto it until the MPU6000 has been initialized. Signed-off-by: Keith Packard

altos: Fix telemega v0.3 igniter order (drogue/main moved). Label ADC dump

2013-05-16T05:11:41+00:00

telemega moves the igniters around so that E/F are now drogue/main. Add custom labels for ADC values to make parsing possible Signed-off-by: Keith Packard

altos: Wait after configuring boot pin before testing it

2013-05-08T04:30:27+00:00

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

altos/stm: Create per-product flash loaders

2013-05-08T04:30:27+00:00

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

altos: Get rodata into flash, make sure sections are aligned

2013-05-08T04:30:26+00:00

.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

altos: Run self loader when application sets boot addr to 0

2013-05-08T04:30:26+00:00

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

altos: Allow STM usb driver to be used without stdio

2013-05-08T04:30:26+00:00

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

altos/stm-flash: Check target flash address against AO_BOOT_APPLICATION_BASE

2013-05-08T04:30:26+00:00

Allows that value to change Signed-off-by: Keith Packard
