Hello, all

Can the QSPI controller and QSPI flash on HiFive Unleashed FU540 board work in DTR mode?
That is to use 0Dh, BDH and EDH commands to operate flash.

Looking forward to a reply.

Thanks,
Hsong

Hi HSong

As we understand from SiFive, there is no DTR Support from the QSPI controller on the FU540 board,
the QSPI flash is supporting the DTR mode but you can’t test it.
