Hi i saw a problem in "etx_ota_update.c" file at line 369

ret = HAL_FLASH_Program( FLASH_TYPEPROGRAM_BYTE,
(ETX_APP_FLASH_ADDR + ota_fw_received_size),
data[4+i]
);

The error is the "data[4+i]" part. It should be replaced with "data[i]"

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.

Hi Can you share any source code on how to implement FOTA via Ethernet for STM32 MCU. Currently I am using STM32H743ZI2 based Nucleo-144 Board

Unable to see eta_ota_app.exe. please upload the same file

Hi

With your code as reference i successfully built and loaded bootloader and user application binaries for "STM32F411RE" evolution kit.
issue :
Bootloader unable to jump to user application. Below is my goto application function
`static void goto_application(void)
{
printf("Loading Application....\r\n");

void (app_reset_handler)(void) = (void)(((volatile uint32_t) (0x08008000 + 4U)));

__set_MSP((volatile uint32_t) 0x08008000);

// Turn OFF the Green Led to tell the user that Bootloader is not running
HAL_GPIO_WritePin(GPIOA, GPIO_PIN_5, GPIO_PIN_RESET ); //Green LED OFF
app_reset_handler(); //call the app reset handler
}`
bootloader storage : 0x08000000 to 0x08007800 [30kB]
Application Flash range : 0x08008000 to 0x08018000 [64KB]

Bootloader is going to error handler while running app_reset_handler() function.

Could you please help me out in solving this issue.
Thanks in advance.

Best Regards
