M: Robe 500i hangs on white screen when try to boot Rockbox

[dr80]

Hi developer,

I followed the instruction on wiki with well tested method a to boot rockbox with the latest build, but the screen hangs at below code:
Rockbox boot loader
Version r20941 :20942M-090516
ATA
disk
mount
Loading firmware
Lenght: D6520
Checksum: 5282085
Model name: m500
Loading rockbox.mrobe500
Sum: 5282085

Could anyone give some suggestion on it? I'm not sure the issue was caused by which part. Is the cracked firmware? modified SVG file? bootloader? Or rockbox build itself.
Thanks for your help!

I also had problems with recent builds. There must be something broken. A discussion on IRC couldn't help to find the problem. An old build worked. I'll have a look which one it is and will share it.

Hi cereal_killer,
Thanks for the information you will provide. It's a good news to all players who own M:robe 500i.
Waiting for your tested work build. Thanks again : )

I had a look and found an old but working rockbox build on my mRobe. I uploaded the content of the player containing the build and the system files here: https://www.file-upload.net/download-14970909/Rockbox_Olympus_mRobe.zip.html (use at your own risk).

Thank you for you help!
The build is works well as expected. But sometimes the screen cannot be activated while the background music is still in playing status. In that situation, the background light is dimmed completely. The phenomenon will occur randomly even if I have disabled the sleeping function. Have you encountered the same issue?

Hi cereal_killer,
sorry to quote you out of the blue, but perhabs you could reupload your rockbox build somewhere?
After i found a working storage solution for my m:robe, i now figured out that basically all current rockbox builds are broken.
Your help would be very much appreciated

I hope everything works. Some time ago, I tried to swap the storage too, but caan't remember if I have ever succeeded or which adapter I used. What do you use?

If that build works for you hit us up here with details and later on IRC when you have some time to test builds

Thank you very much, yes it indeed works pretty well!
I'm using an 64gb msata ssd on a cheap sata to IDE ZIF adaptor, together with another ZIF to CE adaptor.
Initially i wanted to use compact flash, as this sata solution already caused troubles with rockbox on my ipod video.
But the m:robe wouldn't accept any of my CF cards, except my 256gb card i already planned to use elsewhere.
Also it's limited to 128gb, but this CF card has been the fastest and most stable solution otherwise.
The SSD is really heating up a lot, even though the transfer speed never exceeds 1,3Mb/s

Sure, just let me know how i can help you debugging the issue.
Never used IRC before, but i'll have a look around.

to start here is a build with LCD_DMA disabled, I'll probably try a few things, try the builds as you get a chance

also if you would can you make note of exactly how it fails and let me know if that changes when you run a build

like does it take longer flash the screen first etc.

Hi there,

@Bilgus i tested your build yesterday.
It displays "loading firmware" and a few other things, then nothing more happens.
The device also doesn´t respond to the power button being pushed.
No disk activity either.
Exactly the same issue as with the recent dev builds from the download portal i was trying prior.

I think the issue i´m facing differs from what cereal_killer was facing back then.

Let me know if you need more info on that.
Perhabs there´s a way to create a bootlog or something?
