I've tested your changes with OpenOCD: 0.4.0-dev-00931-g6f929db (2009-12-15-13:50) It is working as earlier. For my board lm3s6432 I had to increase work-area amount to 0x4000 to avoid warnings. But still I have a problem that sometimes the first erase/write attempt fails with the following messages: flash write_image erase image.bin 0x1000 bin auto erase enabled Algorithm flash write 2048 words to 0x1000, 16757 remaining error executing stellaris flash write algorithm flash writing failed with CRIS: 0x0 error writing to flash at address 0x00000000 at offset 0x00001000 (-902) Command handler execution failed in procedure 'flash' called at file "command.c", line 637 called at file "command.c", line 352 but the second one always succeeds: flash write_image erase image.bin 0x1000 bin auto erase enabled Algorithm flash write 2048 words to 0x1000, 16757 remaining Algorithm flash write 2048 words to 0x3000, 14709 remaining Algorithm flash write 2048 words to 0x5000, 12661 remaining Algorithm flash write 2048 words to 0x7000, 10613 remaining Algorithm flash write 2048 words to 0x9000, 8565 remaining Algorithm flash write 2048 words to 0xb000, 6517 remaining Algorithm flash write 2048 words to 0xd000, 4469 remaining Algorithm flash write 2048 words to 0xf000, 2421 remaining Algorithm flash write 2048 words to 0x11000, 373 remaining Algorithm flash write 373 words to 0x13000, 0 remaining wrote 75220 byte from file image.bin in 18.802422s (3.907 kb/s) Under Windows it succeeds at the first attempt. Any idea?
