spi problem

[jerly]

Hi:

I use spi0(0x40003000) to wirte data to external flash(W25Q64) with SD8.0(sdk8.0.if I write data without sd, it is OK), and when program run to rx_data[number_of_txd_bytes]=(uint8_t)spi_base->RXD in spi_master.c.and program can't continue running normally. and if the SD make the mistake? or other reasons?

@jerly: Your chip is the latest one (XLR3). So what was the issue when you test with the SPI library from SDK v8.0 ?
