sam3 program firmware check improved #35

Closed cmetz closed 6 years ago

cmetz commented 6 years ago

added a new way to check whether a new firmware needs to programmed into the sam3

sam3s_rpi_sysfs_check.cfg does a flash verify_bank against ch.bin
sam3-program.bash greps the result of the verify after 'contents differ'
reduced the retry counter from 30 to 5, if the program fails
added a short sleep of 1 sec at the end of try_program to be sure everything is fine (not sure if it's needed)

i just recognized, that the sam3s_rpi_sysfs_check.cfg is always performing a "at91sam3 gpnvm set 1" to set the bootloader mode. this is maybe bad, i don't know if the internal flash gets damaged by this, but i will remove this from the code and implement a solution that it is checking if the bit needs to be set, or not.
