I'm using CM4 on a custom made PCB for one of our products. We're design house in Mysuru, Aashaya Designs LLP.
We have manufactured 30 number of boards. So we had ordered 32 CM4 from Silverline Electronics, Bangalore.
We have developed our required software and have fully tested the full product multiple times.
During the process and after completing the full product, we have lost 4 numbers of CM4 boards. They have stopped booting abruptly. They were working fine and all of a sudden, they did not boot. The green activity LED does not flicker or blink.
The boards suddenly stop working. The ethernet LEDs stay on, there is dim red light and no green light. One board is able to enter bootloader mode using the rpiboot and we are able to flash OS to it. The full procedure works fine with the raspberry PI image, but board does not boot.
Other three number of boards, do not even enter bootloader mode. The red LED doesn't glow either. NO response from the board whatsoever.
Out of the 32 boards that we purchased, 4 boards are not usable. That is more than 10%. How do we take forward our product now?
Also there are multiple issues found in this forum. Exactly same issues.
