The SDK version I am using is 07_03_00_29. When I'm using SPI, there are two problems:
1、I configured SPI0, SPI1, and SPI2 in the MAIN domain as interrupt transceiver mode, but when sending a 52-byte data packet, the sending failed, only 32 bytes were sent, (SPI configuration: SPI frame format is 8 bits, rxTrigLvl/ txTrigLvl has a size of 32)。Can you tell me how to solve this problem?
2、When I configure SPI0, SPI1, and SPI2 of the MAIN domain as DMA callback mode, I find that the DMA cached array will be delayed. When the callback function is triggered, the data I read from the DMA cached array sometimes has a packet received data. How to solve this delay problem?
