B4R Question Board Selector Exception error

[tonigau]

First time use B4R, i am getting an error when opening the Board Selector.

An error occurred.
Exception 0xc0000005 0x8 0x0 0x0
PC=0x0
runtime.asmstdcall(0x2a0700060009)

I have ESP32-32 board connected COM12 & can upload sketch with Arduino V2.0.0
I have 2 versions 1.8 & 2.0 Arduino on C drive (need 1.8 for another app, V200 is latest for win7)

I think that it fails to list the serial ports.

Updating .Net Framework might help.

 

[tonigau]

I can see & select serial ports ok in the board selector.
Board type list is empty.

On the Offline PC I updated DotNet from 4.7.0 to 4.8.0, I tried to apply update 4.8.1 but it is blocked (wont install)
no change but some different values in the error report log.
I tried also on my E6440 laptop(win7px64) that already had DotNet 4.8.0 & same issue.

Could this be related to Go V1.21

Could this be related to Go V1.21

Yes. It looks like the Arduino CLI tool is written in Go and it is no longer compatible with Windows 7.

Thanks, I see it here... current version 1.20

arduino-cli command - github.com/arduino/arduino-cli - Go Packages

pkg.go.dev

I tried used Arduini-cli V0.35.2 , I can run it ok by cmd & b4r board selector works.
I expect some possible issues later on being a pre release version of Arduino-cli.

I might have a go at building with "go-legacy-win7", I don't expect a result soon tho.

 

[tonigau]

I did a build of latest Arduino-cli with go-legacy-win7, the board selector is working as expected.
At some time later I can test more of cli only within the scope (board selector, upload, ...) of what I am doing.
It is pretty straight forward to build, took longer to get the go paths right & download all the dependencies (my internet is just kbps in this wet weather)

The Arduini-cli that works on windows7 can be found here...
