Hello
Great finding for the fuze, the only targets without display are now the c200v2 and the still mysterious Clipv2 !
Thanks for the images, but there is already a background image for the Clip simulator here
If you have noticed FS#9512 we miss an image for the Fuze however..
bombjack:
Ok, seems like somebody has been missing something ...
Just trying to figure how things work here.
Anyway: What about this Fuze then?
linuxstb:
The initial version of the Fuze LCD driver had corrupted colours, but that's now been fixed.
funman:
Hello
Good news today: I am able to hijack the Clip OF and branch to my (modified a bit to not disturb the current state) bootloader.
Thanks to the help of mc2739 who helped me testing & debugging the code on his unbrickabe e200, and not thanks to the numerous and still unexplainable data aborts which slow down the procedure, I can now look at the OF state precisely.
Oh and I chose carefully the location where I branch from the OF to my bootloader: it's exactly when the embedded SD card answered "I'm powered-up", i.e. the bit 31 of the response to acmd41 is set.
Yesterday mc2739 was not answering (or just a bit since it appeared in lsusb, but not as a mass storage device); let's hope it works again when he comes back!
For now I checked the i2c registers and the pl180 registers but there is nothing interesting there..
Next step is to check GPIO directions & values (now I can't run the test presumably because of the data aborts).
EDIT1: GPIO checked, they just show what we set in the lcd init routine
EDIT2: GPIO re-checked, before the lcd init routine :-X and they all are on input
If you hackers have a clear idea of what to check just tell it, or contact me to have the hijacking code (I don't want to give it to everybody to avoid people bricking their devices just to be on the razor edge, especially if they don't have anything clever to test)
kugel.:
I'd like to have this code in order to check the Fuze GPIOs. They're more or less unknown at all (except A3).
That should help finding the buttons at least.
