Help! Uploaded CRC is different (25e2595f vs. expected 2080b701)

@Shanian79 Glad you got it sorted.

Hi,
This issue is a long time problem on my side with RRF 3.2 on a Duet 3 MB6HC, one G-Code of 78 Mb in particular just cannot be uploaded regardless of how many times I tried.
Can the network start to introduce issues like this ? I don't see anybody else with the same issue on that firmware so hope it's an easy fix.Thanks is advance for the help, Hugh

@hugsy please post the output of M122 and your DWC version

@hugsy Please Update to at least 3.3 stable
Best
-
@pcr Okay, is there any reports of people having upload issues with 3.2?
I did many modifications to the firmware so the upgrade to 3.3 will take some time. I'll post here when it will be running on my printer. -
@hugsy update is only uploading the ZIP ? you do not have to make andy modyfications

I did many modifications to the firmware so the upgrade to 3.3 will take some time. I'll post here when it will be running on my printer.Reports of upload issues usually come down to either network issues or SD card faults (which can be that actual socket on the Duet). As you're using your own firmware version, it would be best to test the official release, with a fresh SD card, to see if you can replicate the issue. Wireshark trace and M122 following an unsuccessful transfer may be useful.
For SD card/socket faults, see https://duet3d.dozuki.com/Wiki/SD_Card#Section_Troubleshooting_SD_Card_issues

@droftarts I'll try the official release without my motors plugged in and with a fresh sd card to see how does it behave. The printer has special movement that forces it to use a modified firmware so I cannot print with the official release.
The SD card seems to be okay but I'll replace it with something else just to be sure.
I haven't tried Wireshark, I'll give it a try now.Thanks for the help @PCR and @droftarts !

@droftarts Some news regarding this issue, the SD card seems fine but I changed it to another one without any results.
RRF 3.3 stable is solving the CRC issue but in Wireshark there is a lot of TCP flags ("ZeroWindow" and "Window Full") that are present while uploading and not when downloading. These flags are present with RRF 3.3 and also my custom 3.2 build.
I also tried uploading without CRC check with RRF 3.2 and compared the uploaded files with the original files with Meld, and it's interesting :
It seems like there is a cache leak as full sentences end up written in the G-Code, it might be TCP requests but this is beyond my expertise.
As RRF 3.3 stable solves the problem, I'll start building from it. Thank you for your help!

@hugsy If you could post the Wireshark trace, that might be helpful.
@chrishamm can you take a look at this?
