Re: [Openocd-development] openocd-0.3.0-rc0 bug: Fail to write to Intel NOR Flash on AT91SAM9260

[Pieter C. <Pie...@ps...>]

No need to run a git bisect :)

I have confirmed that my hunch was correct.

In

File: src/target/arm7_9_common.c
Function: arm7_9_checksum_memory
Line: 2825

crc_algorithm->address, crc_algorithm->address + (sizeof(arm7_9_crc_code) - 8), 20000, &armv4_5_info)) != ERROR_OK)

I changed the timeout from 20s to 60s. This gave the algorithm enough time to calculate the CRC over 16 MByte and it succeeded.

My suggestion is that this function be rewritten so that the size of the file that needs to be checked is taken into account and that the CRC algorithm is run in for example 1 MByte chunks. Then a 20s timeout per chunk would be fine.

Regards,
Pieter

Pushed to master patch that inexplicably fixes the problem(improve
error handling and output for working area).

Hopefully once we track down the verify problem, we'll find the
real culprit....
