Firmware upgrade through Y modem

[MBhir.11]

Hi ,

i am new to some of the peripherals of STM32 controllers...

I am using STM32L151RCT6 MCU in STMCube IDE for my application..

My requirement is like i need to receive the new firmware binary file via Y modem and need to write into the flash and need to run that application by sending one of the CLI from the UART..

I tried with some examples but not getting proper working of Y modem for receiving the binary file..

Please suggest me if any example codes along with reference document, it will be helpful for me..

it is very much necessary for me....

Hello,

you have some ymodem implementations in the firmware packages:

STM32Cube_FW_F1_V1.8.4\Projects\STM3210E_EVAL\Applications\IAP\IAP_Main

STM32Cube_FW_F0_V1.11.3\Projects\STM32091C_EVAL\Applications\IAP\IAP_Main

STM32Cube_FW_F4_V1.26.2\Projects\STM324x9I_EVAL\Applications\IAP\IAP_Main

There is a readme.txt file in those examples.

Hi Mike,

Thanks for your reply , based on the above examples i prepared one project for STM32L151RCT6 MCU and i loaded it.

passing the binary file from the Y modem Tera term , it is receiving half of the file and stopped shown bellow.

i tried the uart baud rate for both 9600 and 115200 both are showing same behaviour , i am not getting what is problem..

please help me for this .. it is needed for me.

consider the attached y modem function.

Here Y modem h file is attached

It is stopping as shown above

These are flash memory definitions

Hello,

Please, try with Teraterm version 4.85, just to check whether it works. I know that later Teraterm ymodem implementation has changed a bit.

You'll probably have to learn a bit about ymodem protocol too to see why it is stalling.

Hi,

Thanks for reply , i tried with same version of Tera term what you suggested but not solved the issue..

is it related to flash programming ? or any address assigning?
