I'm installing rockbox on the HM-603 Slim 4GB player as per the wiki page
http://www.rockbox.org/wiki/HifimanPortAter rebooting I get a fast rockbox splash followed by the loading screen with
Loading rockbox.rkw
Loading OK
and then nothing - blank white screen. Device apparently hangs - only reset button works.
I can still boot it into the original firmware by pressing any button with the power switch which gets me to
Loading BASE.RKW
Loading OK
Executing
And then the default firmware interface.
I can still rollback to the original firmware, I can still use the original firmware with the rockbox bootloader, but the rockbox itself hangs at boot.
I used both manual and mkrk methods to no avail.
SD card is 32GB formatted using mkfs.vfat on device (that is, without a partition table) and is otherwise visible to the player.
Also during firmware upgrade (both installing rockbox and rolling back to OF) it says it's upgrading HM-801 (probably just a generic message? image file is HM-603.IMG).
What am I doing wrong?
UPDATE:
I got a hold on another (16GB) SD card from a camera and tried booting from it.
This time I managed to see Executing, and the screen did not refresh and go white, but it still hung.
I repartitioned the new SD card making a 8GB fat32 partition, and this time the screen goes white, but pressing any button shuts down the player.
I've also tried cloning git version and building with various developer options (small c build, logf build), but it's the same. Apart from the logf build - it shuts down immediately without interaction.
Though I didn't try to build a bootloader, because I'm afraid to brick the device.
EDIT:
It sometimes goes blank white and sometimes gets stuck at executing with the same configuration.
