Re: Use MC Demo to write user data to external QSPI Flash when use usb audio mode

Are you printing through JTAG? This may mess with the timing of other threads because the whole core can be halted during communication with the host.

Re: Xu224 can't boot up, flash can be written and read

but not clear on how xflash is enabling the QE BIT - is it automatic or do you need to manually pass a parameter to enable QE? QE bit will always be written to 1 when flashing the device using xflash (if you have a QuadFlash device in the XN file). The default is bit 6 register 0, so even not provi...
