| * Add an option (-p) to force use of SB_PLL40_PADDavid Williams2021-02-051-4/+11
| | | | | | | | | | | | When a clock is applied to a dedicated clock pin, SB_PLL40_CORE is no longer the correct primitive to use. Also the name of the clock input must be PACKAGEPIN (rather than REFERENCECLK)

| * | 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>

|/ / / | | | | | | | | | | | | | | | | | | | | | | | | The Lattice tools use these additional commands to read-back the BRAM and CRAM after programming to validate that it was written correctly. `iceprog` doesn't use this right now, so this is just for documentation purposes.
