Clip+ error dc_writeback_callback

<< < (3/3)

johnb:
Hi 1337,

I had a similar message, when my internal flash was about to fail (I can't find the forum post right now).

I believe it paniced, when Rockbox tried to write
.playlist_control
in the .rockbox directory.

Be quick and try Bilgus bootloader that can boot from SD and won't touch the internal memory.

1337:
Hi,

Thanks, Bilgus bootloader works. I wonder if these disk writes eventually break SD card too.

Bilgus:
Everything wears out eventually.
SD cards have a limited number of write cycles just like the flash in your player..
The upside being the SD card can be replaced once it wears out

Also a note for anyone else: While the boot loader works with any version of Rockbox, You have to use a special version of Rockbox *(for the time being) and have the file rockbox_main.<player> on the sd card to enable boot from the sd card

1337:
I was thinking, does clip+ have DRAM that can keep data while device itself is off by draining small amount of power?

1337:
After trying latest stable firmware and boot from microSD, turns out the problem was in microSD 32gb card.
It was formatted to 16kb per sector, after formatting it to 32kb player starts without errors.
