I was wondering if I can get some advice on how best to achieve the same with a Macro, that I can do via the Tera Term UI to transfer fimrware to a micro controller using the ymodem file send interface.
Currently here is what I need to do via the Tera Term UI to upgrade the firmware on an existing ARM based micro controller.
1) Connect to the COMM port to which the Micro-controller has been connected via USB using Tera-Term.
2) Continuously send carriage return/press enter key via the keyboard, while hitting the reset on the Micro-controller, so it breaks into its
3) type "upgrade ymodem" at the bootloader prompt and hit enter.
4) Use the tera-term I send the firmware file via by clicking on the Menu "File->Transfer->Ymodem->Send".
I figured a way to do until step 2. But once the bootloader prompt shows up, I am not sure how to proceed ahead and transfer the file via the ymodem interface to the micro controller.
Has anyone done this before or if there was a forum article addressing something similar, can you please point me to that forum article?
