iceprog: add option for global block unlock

2025-09-13T23:28:24+00:00

Required for some Microchip flash memories. Tested against a SST26VF032. No strong reason to put it as a separate command line option. I'm leaving the part unlocked once the program returns. I should probably re-lock it. This part's lock command seems to be 0x8D, not the expected 0x7E.

Update Claire's name and fix the reference image in the iceprog help

Reset procedure after verification fails and before exiting. Refactor set_cs_creset(1, 1) to flash_release_reset()

iceprog: Improve reset to disable both CRM and QPI

2021-12-17T18:45:34+00:00

It's hard to cover 100% of cases, but this seems to improve probability that a reset works, at least for me on the icebreaker. Some other flash have a different QPI disable command though :/ Signed-off-by: Sylvain Munaut

iceprog: Add option that set QE=1 bit in SR2

2021-12-17T18:44:24+00:00

This is useful when testing litex SoC that rely on that bit being set The setting is non-volatile so it only needs to be done once in case you happen to have used a flash chip that's not by default QE=1 (This has been designed for winbond flash. Others might use different bit ...) Signed-off-by: Sylvain Munaut
