forked from len0rd/rockbox
Fork of rockbox tailored for ipod classic
This patch limits the drawn USB current to 100/500mA, instead of the actual 200/1000mA settings. It also initializes other USB power related GPIOs. Solves some USB disconnect issues: FS#12990, FS#12956. I am using a powered USB HUB with no problems (Vusb=5.05V unloaded), but there are lots of USB disconnects when using the motherboard USB ports (Vusb=4.91V), this patch solves all my issues. Actually, it seems that the USB current drain is limited to 1000mA, when a load peak occurs most USB2 ports deliver more than 500mA, as current consumption increases the USB voltage decreases, an excesive voltage drop produces USB disconnections. Limiting USB current drain to 500mA also limits the voltage drop, preventing subsequent USB failures. Anyway, to minimize voltage drop, it is recommended to use quality cables and preferably connect to USB ports with higher Vusb. Change-Id: I1b931aa18ec93bfd1214e475a72e42893eff52f6 |

Clone 'rockbox' from git (or extract a downloaded archive). $ git clone git://git.rockbox.org/rockbox or $ tar xjf rockbox.tar.bz2 2. Create a build directory, preferably in the same directory as the firmware/ and apps/ directories. This is where all generated files will be written. $ cd rockbox $ mkdir build $ cd build 3. Make sure you have sh/arm/m68k-elf-gcc and siblings in the PATH. Make sure that you have 'perl' in your PATH too. Your gcc cross compiler needs to be a particular version depending on what player you are compiling for. These can be acquired with the rockboxdev.sh script in the /tools/ folder of the source, or will have been included if you've installed one of the toolchains or development environments provided at http://www.rockbox.org/ $ which sh-elf-gcc $ which perl 4. In your build directory, run the 'tools/configure' script and enter what target you want to build for and if you want a debug version or not (and a few more questions). It'll prompt you. The debug version is for making a gdb version out of it. It is only useful if you run gdb towards your target Archos. $ ../tools/configure 5. *ploink*. Now you have got a Makefile generated for you. 6. Run 'make' and soon the necessary pieces from the firmware and the apps directories have been compiled, linked and scrambled for you. $ make $ make zip 7. unzip the rockbox.zip on your music player, reboot it and *smile*. If you want to build for more than one target, just create several build directories and create a setup for each target: $ mkdir build-fmrecorder $ cd build-fmrecorder $ ../tools/configure $ mkdir build-player $ cd build-player $ ../tools/configure Questions anyone? Ask on the mailing list. We'll be happy to help you!
