I'd like to ask for two QSPI specific issues:
1. In the current Linux kernel driver - there is a comment regarding the QSPI working in "IP Command Read" mode:
It states that on Vybrid it is broken and shall not be used. Could anybody from HW design team comment on it?
2. When I do use AHB mode to read data from two SPI-NOR memories connected to QSPI0 bus (individual mode), only 64 bytes are read correctly. The original Linux driver though wants to read 128 bytes:
What is the recommended size for AHB memory transfer size for QSPI?
Thanks in advance,
