Hi,
We have 2 IMXRT1024 board, one configured as master and other configured as slave.
On Master side, lpspi_interrupt_b2b_transfer_master code example from SDK is used.
On Slave side, I'm using lpspi_interrupt_b2b_transfer_slave code example.
Since, I'm using LPSPI2 in slave and LPSPI4 in Master, necessary changes were made in the code (the changes includes : pin mux and interrupt handler, interrupt handler number, LPSPI base address).
My objective is to get data from Master and print it out in Slave console. The master sends 2 bytes of data to slave. I confirmed this by probing on the SDI line of Slave. Ideally, slave should receive this 2 bytes but in my case, interrupt handler is not triggered even though receive interrupt and receive error interrupt is enabled in slave code.
I doubled-checked the hardware connection between Master and Slave.
Master --> Slave
CLK ---> CLK
CS ---> CS
SDI ---> SDO
SDO ---> SDI
On configuration side, both the Master and Slave have the same configuration.
Also here is the image from CRO, Yellow line - Clk, Blue - Data, Pink - CS
What could be the possible reasons for this behaviour?
