|\ | | | | Misc improvements to iceprog
| * iceprog: Use open-drain output to drive SS and Reset lineSylvain Munaut2021-12-171-5/+5

| * iceprog: Improve reset to disable both CRM and QPISylvain Munaut2021-12-171-0/+6
| | | | | | | | | | | | | | | | | | 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>
| * iceprog: Add option that set QE=1 bit in SR2Sylvain Munaut2021-12-171-5/+40
| | | | | | | | | | | | | | | | | | | | | | | | 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 flashSylvain Munaut2019-08-051-4/+2
| | | | | | | | | | | | | | | | | | | | | | 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>
* | Fix piping on windowsTim Pambor2019-08-051-0/+10
|/ | | | 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
* Add -X option to iceprogPablo Cossutta2019-04-271-2/+7
| | | | 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.

* Slightly more robust flash wait function.Piotr Esden-Tempski2018-08-181-9/+29
| | | | | | | 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.
* Add a function to read and decode the status register.Piotr Esden-Tempski2018-08-181-2/+66
| | | | Very useful for debugging purposes. ;)
* Added the FTDI cable pinout for reference.Piotr Esden-Tempski2018-08-181-0/+13
|
* Improved JEDEC ID read function.Piotr Esden-Tempski2018-08-181-4/+30
| | | | | 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.
* Replaced some more magic numbers with FLASH command IDs.Piotr Esden-Tempski2018-08-181-4/+4
| | | | I missed those the first time around.
* Added easier to read chip_select/reset functions.Piotr Esden-Tempski2018-08-181-26/+60
| | | | | | | 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.
* Added more code comments.Piotr Esden-Tempski2018-08-161-16/+39
| | | | | | | | | | 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.
