W5500 DMA with STM32 HAL

Question

Hello, I need to use STM32 DMA (HAL Library) with W5500. I can’t found any example with HAL libs. I have to use HAL because our mcu hasn’t any std library. What’s problem at this code part? BR. uint8_t readByte() { uint8_t rxBuffer; HAL_SPI_Receive(&hspi3, &rxBuffer, 1, 0xFFFFFFFF); return rxBuffer; } void writeByte(uint8_t txBuffer) { HAL_SPI_Transmit(&hspi3, &txBuffer, 1, 0xFFFFFFFF); } void spiReadBurst(uint8_t *pBuf, uint16_t len) { HAL_SPI_TransmitReceive_DMA(&hspi3, w5500.spiRXBuffer, w5500.spiTXBuffer, len); memcpy(pBuf, w5500.spiRXBuffer, len); } void spiWriteBurst(uint8_t *pBuf, uint16_t len) { memcpy(w5500.spiTXBuffer, pBuf, len); HAL_SPI_Transmit_DMA(&hspi3, w5500.spiTXBuffer, len); } void w5500Init() { reg_wizchip_cs_cbfunc(csSelect, csDeselect); reg_wizchip_spi_cbfunc(readByte, writeByte); reg_wizchip_spiburst_cbfunc(spiReadBurst, spiWriteBurst); wizchip_init(w5500.spiBuffer, w5500.spiBuffer); wizchip_setnetinfo(&w5500); wizchip_getnetinfo(&w5500); w5500.result = socket(w5500.socketNumber, Sn_MR_UDP, w5500.localPort, 0); // 0 -> No flag need at UDP }
