Add CRC checking to database entries #2

Closed nthdimtech closed 6 years ago

nthdimtech commented 6 years ago

Check CRC after each read or write and notify client if the check detects a problem

nthdimtech commented 6 years ago

This is covered already by flash ECC checking. Just need to make sure that flash ECC error events are processed correctly

Could you please link here commits which contain the checks for ECC errors and their appropriate handling? I could not find them in the history nor using grep -ir ecc on the whole repository.

More work on ECC error handling needs to be done, that's why issue #6 is still open. I closed this bug to indicate that I was going to use the MCU flash ECC instead of a software CRC. I presently group all errors that occur during writing together and return WRITE_FAILED to whatever command is active while the write was occurring. You can see the code for that in flash_l443xc.c where flash_write_failed() is called.
