Error flashing the QSPI NOR Flash connected to HPS with Command shell

Is it on a development kit or a custom PCB? If custom, which flash are you using?

On our custom PCB we have the same problem when using a Micron MT25QL512ABB8E12-0SIT but it works fine with a Cypress S25FL512SAGBHIC1.

I didn't investigate that much because both the flash are working with our own software, that uses a lower frequency than the quartus_hps command line tool. It could be signal integrity problems but we were careful when routing the board, and adding 33 ohm resistors on the lines didn't change anything.

I haven't found a way to reduce the clock frequency quartus_hps uses either, and if anyone knows I'd be interested.
