Hi there, I want to use the SPI of S32K144 to read data from the 33771 chip.send data with SIP0 By Interrupt mode , which is configured as follows:
Hi there, I am trying to use spi3 of this device to send data to a spi slave. When I send date byte less than 64 bytes it is OK. But when I send more

I want to be able to send an SPI 8-bit transaction of about 32kBytes (so 4000 bits in parallel), but the ESP32-S3 doesn't ever send more than one DMA linked list's worth of data? If I create an spi_transaction_t of 32k, I only ever get about one DMA max payload lengths ...
