* Add iteration over list of frequencies for best solutionMats Engstrom2019-12-311-54/+153
| | | | | | | | | This patch adds support for icepll to try multiple input frequencies to find the best crystal for the desired output frequency. The values tested comes either from a specified file using-B, or from a default set of frequencies from Mousers "normally stocked" crystal oscillators.

| * 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>

|/ | | | 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.
