| Summary | 0000812: IOCTL_NSPI_TRANSFER sends wrong data | ||||
| Description | When transmitting SPI data with IOCTL_NSPI_TRANSFER, wrong data is sent out over MOSI. However the received data from MISO is correct. As a workaround, IOCTL_NSPI_EXCHANGE can be used instead. | ||||
| Additional Information | In SPI_IOControl() the start of the buffer where the data to send is stored is computed wrongly. Two lines are in the reverse order. if (dwCode == IOCTL_NSPI_TRANSFER) { cSpiData.pchWriteBuf = pBufIn + cSpiData.dwCommandLen; cSpiData.dwCommandLen -= dwLenOut; } needs to be changed to: if (dwCode == IOCTL_NSPI_TRANSFER) { cSpiData.dwCommandLen -= dwLenOut; cSpiData.pchWriteBuf = pBufIn + cSpiData.dwCommandLen; } | ||||
