---+ Firmware upgrade
To upgrade the firmware from a Linux box (or from a windows box for that matter), download the .zip file from the mpio website and copy all of the extracted files into the "SYSTEM" directory on your player. Disconnect the player and turn the power on with the AC adapter plugged in. It will go through its upgrade routine and then shut off. Turn the power on again and it will do the upgrade routine once more. The third time you turn it on, you should see the new version number on the splash screen and the player should be good to go! - [[http://www.baerg.ca/mpio_hd200_linux/#firmware][source]], [[http://www.mpioamerica.com/support/hd300_FAQ.htm#Q7][official site information with screenshots for Windows]]

---+ Disassembly pics

Taken from the above site, I hope they are correct and useful

---+ Rockbox port feasibility study

Many (if not all) drivers are written already and needs to be only slightly tweaked:
   1 CPU fully supported (irivers, iaudios, mpio hd200)
   1 Disk access routines as in HD200
   1 LCD routines as in Iaudio M5
   1 Backlight as in HD200
   1 Battery charging as in HD200
   1 Battery reading (aka ADC) as in HD200
   1 I2C uses standard coldfire module
   1 I2S uses standard coldfire module
   1 Codec as in HD200
   1 Keys use mix of synaptic MEP touchstrip and hardware buttons (GPIOs)
   1 USB bridge as in HD200
   1 RTC can use code from rtc_s35390a.c (maybe slightly tweaked)
There are probably some differences in GPIOs assignment compared to HD200.

---+ OF disassembly discoveries
Key handling

GPIO56 - PLAY (active high) GPIO41 - MENU (active low) GPIO45 - ENTER (active low) GPIO51 - HOLD (active low)

ADC1 readouts: NEXT - 250-450 PREV - 600-800 REC - 950-1150

GPIO6 and GPIO7 are used to communicate with synaptics module. The module behaves as rotary encoder.

The 8 pin ZIF connector used to connect Synaptics module has pinout as follows:
   1 VDD_IO
   1 GPIO6
   1 GPIO7
   1 GPI41
   1 GPIO45
   1 GPIO31
   1 GND
   1 GND

GPI36 - /INT1 of s35380a RTC (used by OF as alarm)
GPI37 - /INT2 of s35380a RTC (used by OF as FM alarm)


The 20 pin unpopulated ZIF connector is BDM interface with pinout as described for HD200 with the exception it is MIRRORED.
