This is an extension to the my previous post, Why is a 128GB limit on the size of sd card on radxa zero? - Radxa Forum
With that context, I recently bought a radxa zero with 2GB/8GB config and flashed the emmc with armbian bullseye minimal image. While the zero is able to detect a smaller (64gb) SDXC card, it is not detecting the 1TB SDHX scan disk card. Here are a few things I tried to debug the issue,
- 1 TB card is working (confirmed with multiple pcs).
- Formatted the card on external pcs (ext4/fat).
- Created 200GB partitions to check size limitations.
- Flashed the os in 1TB card and tried to boot, which did not work.
- Tried with Desktop and minimal version.
Here is the dmesg output when inserting the sd card,
