Support hw4 units with AXP2101 PMU
Bootloader successfully compiles and loads onto device.
The LCD appears to be identical to hw3 units.
Scroll wheel and buttons work
Audio output works, including volume.
HP/LO detect works
Rockbox build is generic
GPIO gating logic seems to be working as intended now.
- Added new GPIO definitions - some significant overlaps with pins
from previous hardware revisions...
- Added some GPIO definitions for older players we didn't know about
- Add register definitions for AXP2101 from datasheet
(these are very different from AXP192!)
- Add AXP2101 regulator definitions, need to support multiple step
sizes per regulator.
- Verify AXP2101 voltage set multi-range logic
- Verify AXP2101 voltage get multi-range logic
- Make AXP2101 its own driver
- AXP2101 driver should be "minimally viable", though I think
there is some extra functionality that could be implemented.
- Disabling the coulomb counter stuff - we could maybe make
the E-Gauge work for the same purpose, but it only appears to
be used on the debug screen at the moment so it doesn't seem
like it's worth the effort.
- Found new button GPIOs
- Found error in my GPIO setting logic, blue light works now!
- Set LDO/DCDC output voltages to OF's settings, as far as
I can tell.
- Determined we probably want TCS1421_CFG1:0 to be 0x00,
for UFP behavior
- Tested this rb build with both old and new bootloaders on hw1.5,
hw2, hw4 in as many configurations as I can think of, works across
the board.
- Bootloader can install itself on hw4, so nand chip isn't novel
- Uninstallation file can be made by patcher script, works on hw4
- Installation file can be made by patcher script, works on hw4
- Added HW4 to rbutil, manual

We will install the bootloader with the original firmware's recovery
|
|
mode. The process is summed up as the following:
|
|
|
|
\begin{itemize}
|
|
\item Determine what hardware version your player is and download
|
|
the correct bootloader update file
|
|
\item Place the bootloader \fname{update.upt} file on the SD card
|
|
\item In the original firmware, run the Firmware Update: \\
|
|
\fname{System Settings --> Firmware Update}
|
|
\end{itemize}
|
|
|
|
\subsubsection{Determine hardware version}\label{ref:determine_hardware_version}
|
|
Determine what hardware version your player is. Go to \fname{System Settings --> About The Player --> Version} and reference
|
|
the list below. hw1, hw1.5, and hw2 players all use the same update
|
|
file (with one exception), while hw3 players use a different one.
|
|
|
|
\note{Important: If your player's version is not contained in this list,
|
|
for example if the firmware version is newer than what is listed here,
|
|
we cannot be sure that the hardware is the same. The best thing to do is
|
|
contact the manufacturer and ask them two things: (1) for an update file
|
|
of your version, and (2) if a player with the most recent version listed
|
|
here can be upgraded to the firmware version on your player. If they say
|
|
yes, we can be more certain that the hardware has not changed. These lists
|
|
may not be the most up to date, please see the wiki page at
|
|
\url{https://www.rockbox.org/wiki/AIGOErosQK} for the most up-to-date list.}
|

\item[hw1/hw1.5/hw2 players]
|
|
\begin{itemize}
|
|
\item Aigo Eros Q V1.8 - V2.0
|
|
\item Hifiwalker H2 V1.1 - V1.6
|
|
\item Surfans F20 V2.2 - V2.7
|
|
\end{itemize}
|
|
These players use \fname{erosqnative-hw1hw2-erosq.upt} as the update file.
|
|
The lone exception is the Hifiwalker H2 V1.3, which uses the update file
|
|
\fname{erosqnative-hw1hw2-eros\_h2.upt}.
|
|
\item[hw3 players]
|
|
\begin{itemize}
|
|
\item Aigo Eros Q V2.1
|
|
\item Hifiwalker H2 V1.7 - V1.8
|
|
\item Surfans F20 V3.0 - V3.3
|
|
\end{itemize}
|
|
These players use \fname{erosqnative-hw3-erosq.upt} as the update file.
|
|
\item[hw4 players]
|
|
\begin{itemize}
|
|
\item Hifiwalker H2 V1.9
|
|
\item Surfans F20 V3.4
|
|
\end{itemize}
|
|
These players use \fname{erosqnative-hw4-erosq_2024.upt} as the update file.
|
|
\end{description}
|
|
|
|
Download the \fname{.upt} file for these players from \download{bootloader/aigo/native/}.
|
|
|
|
\note{All players use the same Rockbox build, only the bootloader is different.}
|
|
|
|
\subsubsection{Place update file on SD card}\label{ref:place_on_sd_card}
|
|
Place the appropriate bootloader file on the root of the SD card and name it
|
|
\emph{exactly} \fname{update.upt}.
|
|
|
|
\note{This is a good time to ensure that your Rockbox installation \fname{.rockbox}
|
|
is present on your SD card.}
|
|
|
|
Don't forget to safely eject/unmount your player.
|
|
|
|
\subsubsection{Run Firmware Update}\label{ref:run_firmware_update}
|
|
In the original firmware, run the firmware updater by going to
|
|
\fname{System Settings --> Firmware Update}. At this point, you can delete
|
|
\fname{update.upt} from the SD card if you wish. \emph{Do not delete .rockbox,
|
|
this is your Rockbox installation and needs to stay there!}
