Rockbox Development > New Ports
Cowon D2
shotofadds:
The D2 sim build is now available in SVN - there's no plugins yet, but these can eventually be added one at a time by tweaking the apps/plugin/SOURCES and apps/plugin/SUBDIRS files.
andiator: I'll post another update to read from the flash tomorrow.

Congratulations on becoming a Rockbox Developer, shotofadds 8-)
Yeeze:
Wow really nice progress!!
I got a 2GB D2 model, bought in USA!
The '?' in the output indicates changing numbers xD
Output:
GPIOA: 0xF7FF0?DF
GPIOB: 0x1DE60002
GPIOC: 0x3B000???
GPIOD: 0x07070000
GPIOE: 0x0FFFFFFF
ADC0: 0x03F

Yeeze / andiator: the latest version of the code in SVN will print out some diagnostics from the D2's flash chips. If you're willing to, could you run this on your D2 and report back some information? I can supply a pre-built binary if you don't have the build environment set up currently.
Four blocks of information should be displayed (NAND banks 0 to 4). Each consits of an ID code (5 hex bytes) and a block of 8 hex words. What is the ID code displayed (are they all the same?). Are the larger blocks of data the same for each bank, or all different? (nb: I don't need to know the numbers for the larger blocks of data, just whether the four banks differ).
After this information is displayed, each key press will scan the memory for the word "TAG" - so it should eventually display some readable song names, in amongst some other junk data. Let me know if this does not display anything readable after a few presses.
Thanks in advance.... ;)
(ps. I should state that I take no responsibility if anything unexpected happens to your player, however I've been running this on my own 4Gb D2 for some time with no ill effects. The D2 is my main day-to-day player so I would have noticed anything wrong by now!)
Yeeze: I /think/ at first glance these are the same values my player reports - thanks for the confirmation! nb: ADC0 represents button presses, and I believe ADC1 is a representation of the battery voltage, though this does not seem to update.

I hope, I did not do any mistakes, but it seems like the banks 0/1 are the same as 2/3
Pressing a button counts some MB's and shows some stuff. Seems like ID3-tag content.
Cheers,
Andy
