My BX board is not a complete brick yet, but it feels like its getting close.
After pressing reset or reconnecting, the bootloader fading LED pattern works for between 10-15 seconds before exiting and starting the user program. The time that the bootloader is actually functioning is even less than that, as I can only get 40-50% of a download to complete before it fails. This is driven by something time-related, because the amount downloaded before fail depends on how quickly I download after pressing reset. I have a desktop and a laptop both with ubuntu 18.04. Both exhibit the same behaviour with slightly different times. If I connect it to my Win7 laptop, the bootloader works fine indefinately and downloads without issue.
At one stage I did successfully download from my ubuntu desktop multiple times without issue.
I haven’t had any failed attempts to update the bootloader, only failed attempts to download my own program. I assume they’re targeting different areas?
I’m not a linux native, so I’m a bit stuck where to start looking.
Should I refresh the bootloader from my Win7 machine? If so, how do you do that when it’s up to date?
Update: turns out it was ModemManager. Created a rule to have it not target this device and the rest is history. Sorry for not researching harder.
