How did you configure the code?

Besides, how does it work if you use this solution ?

Hi

In order to enable ssel0, we need:

1. config ssel0 pin in pin config tool. for example (this screenshot is from LPC55s69, but same for your device)

after generate code, new pin_mux.c will  include ssel0 pin initialization code

step 2. set TXSSEL0_N FIFO write data register to select ssel0 spi device.
