Rd1071 Rca Lyra/stmp3410

Expand Post »
I own a RD1071 RCA LYRA MP3 player. I was wondering if anyone knew what programming language it uses. The main chip is the STMP3410. It handles everything good. I can update the device with new firmware and I would like to change it a little.

The update files are here if anyone has a decompiler for many languages. Uninstalling it is clean.

Re: Rd1071 Rca Lyra/stmp3410

not much you can do with it, maybe if you want to dump the bios, you could learn the USB protocol, but other than that not much to do.

what are you trying to accomplish?

Re: Rd1071 Rca Lyra/stmp3410

Anyone recommend a free compiler/decompiler? Any size, I have DSL. What I am trying to do is fix a few errors/glitches with the playback. It really is an excellent MP3 player, but it shows DOS-type file names and skips a tenth of a second or so of playback.

All I need is something to read the update files. If it gets corrupted or has a new update it erases the BIOS fully and reinstalls.

Try OLLYDBG (google it to find a download) its a good quality free debugger/disassembler (decompilers do not exsist).

Goodluck.

Re: Rd1071 Rca Lyra/stmp3410

Every file that is put into the device is like this. Hex and the letter s make up everything. I did try OLLYDBG and Source Edit but nothing makes code out of this. It was made with something...
