STM32C092 (TSSOP20) FDCAN Bootloader

[Sanderthunder]

Hi everyone, i just want to be sure cause it's the first time playing with the bootloader.

I have a STM32C092 (TSSOP20) an i was wondering if i can flash it through FDCAN, but reading the AN2606 i unfortunately found a postilla as following (page71):

Flashing through can with a TSSOP20 isn't possible, after a second look even the datasheet said the same thing.

So there are any other method to flash through FDCAN?

My only option seems to be boot from RAM and writing my own bootloader into the application, it's that correct?

Thanks,

Sander

You have interpreted things correctly. As the documentation implies, the only method to flash through CAN on that chip would be to create your own custom bootloader. This will require you to first flash the bootloader using some other method.
