%TOC% ---+ Port Status | *driver* | *status* | *comments* | | LCD | %GREEN%90%%ENDCOLOR% | Only one type of lcd implemented. No inverse and other fancy stuff. | | Backlight | %GREEN%100%%ENDCOLOR% | PWM frequency is quite low ~500Hz but my backlight driver circuit can't cope with higher freq reliably. | | Buttons | %GREEN%100%%ENDCOLOR% | Hardware keys for generic/reference design. | | I2C | %GREEN%100%%ENDCOLOR% | Both internal bus to the codec and external supported. | | SD | %GREEN%90%%ENDCOLOR% | Basicaly works. DMA handling is suboptimal. Needs more testing. | | NAND | %RED%10%%ENDCOLOR% | Low level driver part is reverse engineered. The work on reverse engineer FTL scheme is started.| | PCM | %YELLOW%80%%ENDCOLOR% | PCM driver implemented but playback is choppy on some players. | | Codec | %YELLOW%90%%ENDCOLOR% | Driver for internal Dolphin codec implemented but not much tested. No support for anything else than playback through i2s or analog bypass for FM. | | Recording | %RED%0%%ENDCOLOR% | Not implemented. | | ADC | %GREEN%100%%ENDCOLOR% | | | RTC | %RED%0%%ENDCOLOR% | Not present in my device. From various documents it seems that HYM8563 (PCF8563 clone) is widely used. Some members of the rk27xx family have internal RTC. | | FM | %GREEN%100%%ENDCOLOR% | RDA5807P driven in TEA5767 compatibility mode. Only in analog bypass mode for now. | | USB | %YELLOW%90%%ENDCOLOR% | The driver is not yet merged see [[http://gerrit.rockbox.org/r/#/c/364/][patch]] on gerrit. There are still some minor issues to be solved and more testing is needed | ---+ Running custom code One may compile rockbox bootloader (which currently is playground for testing code) and execute this on the device with help of rk27load utility (located in utils/rk27tools/rk27load) As of r30459 it is possible to compile and run main rockbox binary, codecs and a few test plugins. -- Main.MarcinBukat - 07 Jun 2011
