in xn file, i add M15P16 connect define (use FL_DEVICE_NUMONYX_M25P16 configuration) , i can compile and write xe file to M25P16, but boot up fail ( no data output on SO pin of M25P16 when power up ). where shall i modify ? thanks

XCORE-200 can boot from QSPI (default) or standard SPI flash devices. You have standard SPI flash mapped.

Please confirm if you have applied the external pull-up to force the XMOS CPU to boot from standard SPI flash. A value of 4k7 should be used for the pull-up resistor to override the internal pull-down resistors.

Thanks for your reminding, mon2,
As our board used QSPI flash, XOD4-7 use for data pin, XOD4 is not pulled-up with 4k7.
