Hi,
I am testing the Bootloader and App.
I have problems with the CRC using UART.
When I send the SOF from the APP, the bootloader gives me error when calculating the CRC.
And the other way around too. If I send the ACK from the Bootloader to the App, the App also gives me an error in the CRC.
Inside Bootloader "etx_receive_chunk( uint8_t *buf, uint16_t max_len )" function:
if( cal_data_crc != rec_data_crc ) { printf("Chunk's CRC mismatch [Cal CRC = 0x%08lX] [Rec CRC = 0x%08lX]\r\n", cal_data_crc, rec_data_crc ); ret = ETX_OTA_EX_ERR; break; }
I get:
cal_data_crc = 0x8B329C8
rec_data_crc =0x4E08BFB4
I am using CubeIDE's hCRC component, but I don't see that anything can be configured this component.
In the other direction, the same thing happens to me...
In function "etx_ota_send_resp( ETX_OTA_ACK );"
The rsp.crc = HAL_CRC_Calculate( &hcrc, (uint32_t*)&rsp.status, 1); give me the crc=0xc704dd7b
{sof = 170', packet_type = 3, data_len = 1, status = 0, crc = 0xc704dd7b, eof = 187}
In the App I get:
CRC Received: C704DD7B
CRC Calculated: 4E08BFB4
Any idea what the problem might be?
Thank's a lot.
