Hi All,


I  make custom bootloader based on  X-CUBE-IAP-USART example, all works fine except I can't transfer a firmware .bin file using ymodem if the .bin file is above 256KB.

I use STM32F429XX that have 2MB Flash, and my firmware that want to be flashed is above 1MB.


Are anyone was got success to transfer a firmware above 256Kb using using official ST example? or that is the max file size for ymodem can accept?
