Dear all,
I recently encountered a similar issue with my EmonPi, which I suspect was due to an SD card failure. After unplugging and restarting the device, it became stuck on the boot screen. I attempted to resolve this by installing the latest image (01Feb24) on a new 32GB SD card. However, this resulted in a continuous stream of “sysrq: HELP: …” messages, interspersed with occasional boot messages. Despite waiting for the check process to complete, the issue persisted and the EmonPi stayed in this status.
I then tried a different approach: I flashed the 10Nov22 image on the same new SD card. This image only required 16GB, so I created a temporary partition to allow for future data partition expansion. After inserting the card back into the EmonPi, it booted without any problems.
Encouraged by this success, I shut down the device and installed the 20Nov23 image on the same SD card, again creating a temporary partition. The EmonPi started up without any issues.
However, when I repeated the same process with the 01Feb24 image, the “sysrq: HELP: …” flood messages reappeared. Given that the SD card is new and functions correctly with previous images, and there are no apparent issues in the logs with those images, I suspect there might be a problem with the 01Feb24 image or when flashing the image (?).
FYI, I used BalenaEtcher 1.18.11 to flash the image.
