2025-09-13iceprog: add option for global block unlockHEADmainIan McIntyre
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.

2021-12-17iceprog: Improve reset to disable both CRM and QPISylvain Munaut
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 <tnt@246tNt.com>
2021-12-17iceprog: Add option that set QE=1 bit in SR2Sylvain Munaut
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 <tnt@246tNt.com>

iceprog: Better reset of flash
2019-08-05iceprog: Better reset of flashSylvain Munaut
If the flash was in a 'weird' mode (like CRM, QPI, ...), sending a continuous stream of 0xff should take it out of it. It looks like the previous code was trying to do that, but was only transferring 8 bits and then 2 bits which is way too short. Signed-off-by: Sylvain Munaut <tnt@246tNt.com>
2019-08-05Fix piping on windowsTim Pambor
On windows stdin and stdout have to be set to binary as otherwise windows treats it as text and converts occurences of CRLF to LF
2019-04-27Add -X option to iceprogPablo Cossutta
In my setup, in OSX I have problems reading from libftdi but not writing. In case of a failure iceprog exits and leaves the FPGA in an useless state. I think it would be a good option to have the possibility to skip the verification process.

2018-08-18Slightly more robust flash wait function.Piotr Esden-Tempski
In cases when the FLASH chip is bit flaky and the status register "bounces" this flash_wait should be able to perform a bit better. Also added more verbose output around block erase.
2018-08-18Add a function to read and decode the status register.Piotr Esden-Tempski
Very useful for debugging purposes. ;)
2018-08-18Added the FTDI cable pinout for reference.Piotr Esden-Tempski
2018-08-18Improved JEDEC ID read function.Piotr Esden-Tempski
The function now checks how long the extended JEDEC ID field is for the particular FLASH chip and only reads the amount provided by the chip.
2018-08-18Replaced some more magic numbers with FLASH command IDs.Piotr Esden-Tempski
I missed those the first time around.
2018-08-18Added easier to read chip_select/reset functions.Piotr Esden-Tempski
Just calling a gpio function with two numbers was not very self explanatory. The functions now refer to the actual indended action, chip (de)select for flash, reset and chip (de)select for sram. Reading the code and understanding what steps are taken should be easier now.
2018-08-16Added more code comments.Piotr Esden-Tempski
Main point was to group the code into three logical segments: * MPSSE/FTDI defines and functions * FLASH defines and functions * iceprog implementation core While I was at it I also added a few comments for stuff that was not immediately obvious what it does.
