stm32F769I IAP

[Aravind1]

Hi,

I am trying to implement IAP through UART on stm32f779I Evaluation kit,  I am using stm cude IDE 1.9.0 and F7v1.17.0 software package.

I have downloaded IAP_Main project using st_link. By using tampered button entered into the downlaod mode and using teraterm tried to load the binary file of IAP_SingleBinary_Template example code from the examples through YModem protocol. My IAP is working fine but when it comes to downloading the binary file teraterm is showing only 2 packets is loaded and the file transfer window is getting disappear.

Can anyone please help me to find out the issue.

 

Thanks & Regards,

k. Aravind

Not sure of the robustness of the Y-MODEM implementation. You're probably going to need to do some bus analysis on the serial port traffic, and/or add some SWV based telemetry to the STM32 side code so you can understand specifically what's happening. 

Familiarity with the protocol would help. Perhaps try other implementations, or your own.
