Hifiman HM-801: Newer builds became unstable. Can I help?

[speachy]

I haven’t had a chance to test the latest build yet. However, I’ve encountered a different kind of problem, which I believe relates to the hardware section. I bought a new microSD card, the 'Samsung Micro SDXC EVO Plus 512 GB,' and found that Rockbox doesn’t work with it on the HM-801 — it just freezes. The stock firmware, on the other hand, works perfectly. This is a modern microSD card, while Rockbox works fine with my older one. My friend also had the same issue with a modern SDcard. Is addressing such compatibility issues too big a challenge, or is it something that can be resolved?

It's going to take low-level bus analysis to know what's going on with one SD card versus another, and see exactly where things go awry.

perhaps the format is screwy? might try using dd to zeo the whole drive and reformat + re-partition it

What is "dd"? I’ll try, of course. Could you please name the software?

Okay, but is it even possible to do this? It’s not at all obvious to me from your message.

There's a chance that I found my mistake. When switching to a new card, I should've copied the Playlist folder on the card also. Will report tomorrow.

Unfortunately, your advice didn’t help. Rockbox seems to have a limitation with microSD card technology at the moment with the HM-801. I’ll need to use older ones until there’s a way to address this limit.
