Hi,
I would like to know that how to update the firmware or write firmware for LC2093-B (heart for chinese mp3 player) based devices using any kind of specials tools which the manufacturer/developers use?
How can I write the firmware from scratch if possible? I am keen to work on this simple decoder which is low cost, low voltage chip for my future projects.
I could not find its datasheet anywhere, no technical specification is available.
Any help in this regard would be appreciated.
