Thank you for that link, unfortunately got nowhere.
You link and the previous post mention a UART. We don't have any UART output in our Compute Module carrier board and we have no way to tap into any trace or pin reaching the UART IOs. Hence my previous questions left unanswered about using the uSD card instead (if possible?) and the request for clarification about the UART.
So in summary:
- we use a Compute Module LITE
- carrier board has the micro USB connectivity for a PC (i.e. the circuit is the exact copy of the reference/official CM IO board including the jumper enabling eMMC
- Ethernet connectivity
- no UART access whatsoever
I appreciate your help and understand you are busy, but could you please address each of the following separately and clearly because I spent the whole day and night (now 3 a.m.) trying to figure out things from the brief replies above and got nowhere.
1. Is the boot log you requested to post here on the uSD card?
2. If after switching off the previous boot log remains then I could just copy that file using a uSD card reader? Or do I need to have real time connectivity to a PC?
3. in each of the cases where do I find the boot log?
4. I assume the boot log file name is actually bootlog? What extension?
5. The post you shared mentioned formatting the uSD card and installing ONLY the bootcode.bin. It didn't work and to be honest after seeing the tony size of that file I would not expect it to because there would not be any OS installed (i.e. again we are using the compute module LITE)
Could you please address each question separately and (because of my lack of knowledge of the PI platform) very clearly (rather than short quick links which would obviously assume a Pi knowledge that is not there
Once again thank you for your help
