I was able to configure all my buttons if I choose the RK2700 chip configuration.

Hope this might help anyone still playing around with RK27xx players and the SDK.:mrgreen:
Thank you for you effort =)
I've tried this, it works! But... The sound is MONO, not STEREO. And, OF uses vol_out | GAIN_BYLEFT, so it's is misconfiguration in other piece of code.
I'm working on this because for now it's only one problem that preserves me from using Rockbox on RK27XX - i've got FM, RTC, ADC buttons, etc working, but playback quality is low, and problem seems to be very similar - it exists on both my players (RF-8800 and RF-8900) and in both Rockbox and SDK builds. I've even tried to take some parts of code from newer TEXET T-900 SDK, but with no luck.
