- implement flash driver
- see arch/arm/src/stm32/stm32_flash.c and related
- both banks could be mapped with care taken not to erase the active code.
- both banks could be mapped with care taken not to erase the active code.
- perhaps the MPU could block code corruption?
- once implemented, the free() cmd replacement can show flash information.
- once implemented, the free() cmd replacement can show flash information.
- Seen crashes when running serial ports below 921600
- COM34 (UART1, ttyS1) runs the smoothest with 'serialblaster' test...
the other two (UART0, USART1) seem to stutter...
- created a cpuhog test. Each instance takes a semaphore, burns cpu for 6ms and then releases
the sem to exercises semaphores passing and a busy cpu. The first two instances become a
producer/consumer pair using a pipe (FIFO) to exercise the fileio data passing.
-> no crashes with 8 instances running. (No MMU, No BASEPRI)
-> no crashes with 8 instances running. (MMU + BASEPRI)
-> not however that the serial ports are very finicky with BASEPRI enabled!
This setup sends single charactes for each produced or consumed block,
and doesn't seem to have any issues:

- USB serial not quite stable when pushing lots of data
- UARTs don't use DMA. We may need this for high baudrates.
- Inbound hardware flow control requires dma.
- Inbound hardware flow control requires dma.
Current Test:
40mA: 120Mhz (240 MHz PLL) with SDCard mounted, UART0+UART1+USART1 enabled, USB Device availible (but nothing plugged in)
37.8mA: 120Mhz (120 MHz PLL) with SDCard mounted, UART0+UART1+USART1 enabled
16.9mA: "" with WFI added to up_idle()
