描述

When using GQSPI, it is possible to use a byte transfer to send dummy cycles instead of using CS hold time.

QEMU does not emulate link state for GQSPI commands, so if sending 1 byte using quad or dual mode, QEMU will send 1 cycle to flash instead of 2 or 4 respectively.

解决方案

To work around this issue, use CS hold time for the amount of dummy cycles you need for your command instead of transferring bytes.
