I have a a very unusual problem for a GHI product, and the G120 SOM. They’re rock-solid. They’re so reliable that we assume they’ll work fine and use the SOM to run our board diagnostics.
Several G120 SOM modules which were installed by a third party on our custom circuit board. They are loading fine, but failing to run. Some modules won’t talk to the USB debugger at all. Some will boot, but deploying the application fails. Some will boot, take the application deployment, and the basic features work fine up until the application starts running, then they either crash without throwing an exception or throw an exception, then crash.
I’ve done very careful checking to make absolutely sure that the loader and firmware are correct on these boards.
So, I’m suspecting the SOMs were damaged in some way during installation. Are there any low-level diagnostics that will progressively test the SOM to failure, so we can see what went wrong? And, if not, is there something GHI can do with one of these SOMs that has been removed from a board?
