Iriver E100 Port thread
« on: September 22, 2008, 09:20:14 AM »
just getting back on topic... no a port doesnt look likely.. the main chip has a wonderful iriver branding and we have absolutly no idea about it.. also the firmware image we have is encrypted so we cant get clues from that either

Edit:  Changed title and made this the first post

Using PMs to annoy devs about bugs/patches is not a good way to have the issue looked at.

After a little bit of searching it looks like the "iriver2135" chip is the ATJ2135 which has a MIPS 4KE core and a DSP.

about the E100:

I just wanted to add in a few comments about the firmware. It appears to use a central SQLLite db file to map all the directories, playlists, etc. This db file is created by the proprietary software on the pc, that is included on a cd-rom with the player. I think it is transferred/updated to the player when the unit is synced on the pc.

I was able to obtain a sample playlist (.pla) from iRiver support. It's a binary file, and I've attached a copy below (just rename the extension to pla...had to change it since it's not one of the allowed filetypes...). I tried to use a binary editor to modify this file for a couple of mp3's I placed in the Music directory on my E100, and I made sure to keep the header and footer of the sample file intact. However, while the E100 recognized the .pla file, it gave me an error saying it was empty.

Next, I found a playlist editor someone wrote for the Sansa e200, and that got me the same result (no need for tedious binary editing). I started modifying that program to the specifics of the E100 -- but in the end it won't work since the player will see the .pla file as 'empty'.

All I really want to be able to do with my E100 is create valid playlists without the proprietary Windows-only software included with the device. But hopefully this information will be useful as well to anyone willing to write a Rockbox port.

A firmware upgrade file is currently somewhere on my site

JdGordon has an E100 and he already opened it, he could add info to the wiki

Nice thing about the E100: it has line-in :)

I deleted a bunch of posts speculating about iriver releasing an SDK someday.

On the upside, someone working on the LPlayer port found a datasheet for the E100's CPU and posted it in the wiki:

Hi! Is there any progress in decrypting E100 firmware?
I have the Transcend MP860, he also ATJ2135 and similar firmware with the first byte 11 22 33 44 55 66 77 88 99 aa bb cc dd ee ff. Firmware on the E100 and the MP860 can be changed using Firmware Develop Kits http://www.multiupload.com/IZLRSDQTVK, and it has a library EncryptDll.dll.
Maybe it will be useful.

Would it help if i desoldered the large components on the PCB using hot air station and made hi-res photos of both sides of the PCB so we see the traces underneath those large components? I have 3 E100 working and another two that are broken.

Not really since we have schematics.
