Issue #252: flash command writes to SPI-NOR unreliable

flash command writes to SPI-NOR unreliable:
Hello,

Flash command writes random junk data to SPI-NOR. Verification fails and one can spot blocks of junk data in read-out Flashrom via Buspirate5 binary mode flashes fine.

Please fix and let me know if you need further details.

What is the chip and size?

Does the flash command verify fail or succeed?

Can you post the output of the flash command so I can see how the JEDEC info is being read?

Would really like to look into this further, but it would be helpful to know the information above.

Was hoping to get some additional info, but I’ll do my best to look into this anyway.

the flash command should be updated with the new hex viewer anyways.

Sorry, the issue was due

Sorry, there was no reason to blame. The issue was due to cable length and absense of shield. After I shielded the flashing TagConnect cable with copper tape, all went smoothly.

Thank you for the prompt responce and hacky & useful tool.

Thank you for the update.

Because of your query I update the flash command with a new dump action to show the contents of the chip :slight_smile:
