Dear engineer,
In S32K144 working in (Run mode), SPI0 as slave (using DMA), PLLCLK=160MHz,LPSPI0_CLK=BUSCLK=80MHz;
I would like SPI's Baud Rate>20MHz, but when sending data using a 21.5mhz host (STM32), S32K144 will have partial data errors (high half byte of random bytes).The project configuration is shown in the following figure:
The data is correct on the SPI bus, but there are always a few bytes in the S32K144 RXBuffer (20 bytes) that are wrong (Baud Rate>12MHz, less than 12MHz host send interval less than 2ms will also be wrong).
Hi,
Regards,
Lukas
Dear engineer,
Thank you very much for your reply.
