Error during board uninit and no ACK after that #1713

Closed vacagonzalo2 closed 3 months ago

Intended use

I want to flash and erase my target (multiple times if needed) from a Raspberry Pi. I have to use a raw binary in this case, I cannot use the HEX format.

Result

I was able to program the target and its working. However I can only erase or re program it from a vendor's IDE (MPLAB X).

Note: with the HEX format (Intel format) everything works great.

Hello, I never worked with ATSAMC20 series, but I think you need the cmsis pack file for this family to make things work. You can download it at https://packs.download.microchip.com/, or directly by this link: https://packs.download.microchip.com/Microchip.SAMC20_DFP.3.5.93.atpack Then, add this argument to your command line: --pack <path-to-pack-file>

vacagonzalo2 commented 4 months ago

@hagibr thank you for your response. Yes, I had installed the pack with the command: pyocd pack install atsamc20e18a

If I run pyocd pack show, this is what I get:

ifupper@raspberrypi:~ $ pyocd pack show
  Pack             Version
----------------------------
  Keil.SAM-C_DFP   1.4.3

The problem seems to be that I cannot flash the target more than once. I have to erase it from the IDE.

This problem is also present on Windows 10 pro.

I was able to avoid this problem by excecuting pyocd erase --mass --target atsamc20e18a before loading the binary.
