Hi

hi, did anyone manage to get katapult working with stm32F042. Issue is I have I have managed generate canboot.bin. Get UUID and upload test program but here us problem when testing simple blink cannot get it working either my test program or canboot back after testing simple blink program is first time uploaded. My boot pin is floating atm. Just wondering if any can advise. Or have some experience with katapult custom canboot loader. Ps. After 1 upload via uuid Hex file still show CanBoot on microcontroller

What is "katapult" in the context of microcontrollers?

What do you mean by "katapult" here?

This: https://katapult.io/ ?
Or this: https://github.com/Arksine/katapult ?
Other ?

Always best to give a link so that people know for sure what you're referring to!

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

Yep

my bad. I meant katapult by —-https://github.com/Arksine/katapult

still trying to make bootloader usable. For this controller. :beaming_face_with_smiling_eyes:

Like to mention that I’m not trying to use with any printers at all. Idea is to use just to be able to upload software via can since canbootloader is not available by default by ST. On stm32f042F6P6.
