Itech IT8511A+ segmentation fault #35

Open spike77453 opened 3 years ago

spike77453 commented 3 years ago

Describe the bug Adding a new IT8511A+ device results in segmentation fault

To Reproduce Steps to reproduce the behavior:

  1. Go to 'Add device'
  2. Pick ITECH IT8500 driver
  3. Select 'Serial port'
  4. Set baud rate to 115200
  5. Click on 'Scan for devices using driver above'
  6. Select 'ITECH 8511A with 3 channels'
  7. Click on 'OK'

Expected behavior A new Itech 8511A+ device in the device tree

Screenshots or log Screenshot_20210802_011124

Clicking 'OK' in the screenshot above crashes smuview

Enviroment (please complete the following information):

Could you please start SmuView with full log output and attach the whole output here?

This is for connecting the load with the (factory) default serial settings (9600/8n1). Maybe you have to adapt the TTY:

./smuview -d itech-it8500:conn=/dev/ttyUSB0 -l 5

When looking into the sigrok device driver, 38400 should be the maximum baud rate (not sure, I don't own that device):

./smuview -d itech-it8500:conn=/dev/ttyUSB0:serialcomm=38400/8n1 -l 5

Thanks for getting back to me, really appreciated.

Just for the record, factory default setting on my unit is 115200 8N1. I've set it to 38400 though. Output with the version that was compiled with -Wp,-D_GLIBCXX_ASSERTIONS:

Fixed :) The cause of this issue was, that SmuView couldn't handle the unexpected AC flag for the power channel.

Now signals can be added to "fixed" channels: https://github.com/knarfS/smuview/commit/ca7951b2cc9db614c152123171960b883aaa9bc5 And the AC flag was removed in the sigrok driver: https://github.com/sigrokproject/libsigrok/commit/24be1e05d5f1cbe84c69b0bd27d422ad4b13cd77

main() failed:  invalid argument

New builds can be found here: https://copr.fedorainfracloud.org/coprs/spike/sigrok/builds/ Should I open a new issue?

knarfS commented 3 years ago

I've looked into this and I think the Itech driver (for whatever reason) returns a SR_ERR_ARG somewhere down the line from api.c, config_get(), which finally throws an exception in the libsigrok C++ bindings (from your log: main() failed: invalid argument).

I've done some experimental changes in SmuView to catch this exception and output some error messages, which will hopefully help us to figure out the root issue.

It would be great, if you would build my SmuView itechbranch (https://github.com/knarfS/smuview/tree/itech) and then attach another log.
