LPSPI_IP_BUSY state while transmitting data from Lpspi_Ip_AsyncTransmit() function

We have  an issue With S32k44,

configured LPSPI using EB tresos and tried to transmit data using Lpspi_Ip_AsyncTransmit()

call gets executed once Other calls are rejected because the drivers stay in the LPSPI_IP_BUSY state.

Can you please share an Example project of S32K344(with EB tresos configuration)

for Lpspi_Ip_AsyncTransmit(); using DMA?

#S32K344

Hi,

try to look over below example, not for EB but is using HLD driver as well.
