5 years agoHi,
thanks for the answer. For writing to the flash, I was following exactly the steps given by the Dev Kit user guide for writing the CFI via the MAXV.
As it seems, the pof I generated was actually correct.
I was able to successfully write the flash after I lowered the USB JTAG frequency in the programmer to 2MHz. By default, Quartus sets 24MHz for the USB JTAG which does work for direct sof config, but not for flash.
With 12MHz, it usually fails somewhere in between, which tells me this is really a clock related issue.
I did not find any note on the JTAG frequency in the user guide, however. Can anyone confirm this?
The other questions remains: the sof2flash example from the user guide does not work when I execute the given command.
