STM32G474 IAP bin file transfer stopped according to AN4657

Hello,

Now I am designing a IAP program for STM32G474VET6 according to the AN4657 referred to STM32L476G_EVAL. and I used VScode +CMake tools.

I have modified the flash_if.h because of the diffrence between STM32G474VET6 and STM32L476G as below

 

 

/* Define the address from where user application will be loaded.
   Note: this area is reserved for the IAP code                  */
#define FLASH_PAGE_STEP         FLASH_PAGE_SIZE           /* Size of page : 2 Kbytes */
#define APPLICATION_ADDRESS     (uint32_t)0x08008000      /* Start user code address: ADDR_FLASH_PAGE_8 */

/* Notable Flash addresses */
#define USER_FLASH_END_ADDRESS        0x08080000          /* STM32G474VET6, Flash 512KB*/

/* Define the user application size */
#define USER_FLASH_SIZE               ((uint32_t)0x00008000) /* Small default template application */

 

 

 and modified the flash_if.c as below

 

 

/*  512KB flash 1 * 512 * 1024 */
#define FLASH_START_ADRESS    0x08000000
#define FLASH_PAGE_NBPERBANK  128
#define FLASH_BANK_NUMBER     2

/* Unlock the Program memory */
  //HAL_FLASH_Lock();

 

 

the issue I met is when I used Tera Term to transfer an APP bin file, the transfer stopped and the result is time_out as below

I am sure that the UART is OK because I can receive the menu strings and send 1 for choose download.

I will attach the project file as attachment(it seems cannot attach), please give me some advice.

Best Regards,

Chester

Hello, @SofLit  @Tesla DeLorean @MM..1 @Imen.D 

 

what is the issue?

I attached the project file. please have a check.

Could you give me some advice?

Thanks a lot!

 

First try explain why you dont use internal system bootloader, and second why you dont scope signals and debug...

How is your TT COM config?

hello, @MM..1 

1. I want to study IAP and then expand to OTA. I am not sure use internal system bootloader can expand to OTA or not. I searched ST.com, then I get the AN4657 about IAP. can internal system bootloader expand to OTA? please give some guide.

 

2. I have debug to step into code, it seems HAL_UART_Receive() had a timeout always for the first byte. another guy had the same issue with me, he also posted a question, but no results from you all. 

 

3. TT COM config as the AN4657 required, as below

send bin file as below

dqsh06_1-1736988603152.png

is something wrong?

if my TT config something wrong, how can I get the menu strings and I sent 1 for choosing download?

please give some advice.
