u-boot loads that partition in memory and tells the kernel about it through kernel command line argument like ntxfw_p= and ntxfw_sz= in board/freescale/common/ntx_comm.c.Backlight still work with the unknown data removed. ntxfw contains backlight tables, and some unknown extra data that is not described in structs and doesn't seem to be used.hwcfg only contains hardware configuration data and a lot of zero padding.Modes: Unknown (no mode version specified) Number of temperature ranges in this waveform: 14 ntx-partitions-parser/partitions/waveform.imgįrontplane Laminate (FPL) platform: 0x0 | 2.0įrontplane Laminate (FPL) size: 0x0 | Unknownįrontplane Laminate (FPL) rate: 0x85 | 85Hz A quick look in mxc_epdc_v2_fb.c tend to indicate that there is only data in this waveform partition.That data was analyzed with inkwave as shown below.That header also contains some RAW data which seem to only contain waveform data: a mxcfb_waveform_data_file struct header.Document how to do bootloader development (device recovery, usb boot, etc).check what driver/cards the free wifi firmwares work on.Hardware: describe the hardware better and look again if there is anything dodgy (unlikely to be missed with the software review though).Linux source code: Look at the dts and drivers again to spot if something was missed. u-boot source code: Read it to see if it loads any firmware.e-paper display: validate its usability better if possible.Hopefully it is small and the CPU ISA is known. The WiFi firmware is under the GPLv2 but lacks source code.So far only devices using the arch/arm/boot/dts/im圆sll-e60qm2.dts devicetree were reviewed.So for instance the instructions that explain how to make the display work with free software are only meant to validate that part, and didn't necessarily remove unrelated nonfree software. This doesn't mean that merely following the instruction will automatically make the source code respect the Free software distributions guidelines or that the device would automatically respect the Respect Your Freedom certification. The instructions given here are meant for research purpose: they are intended to find out if the kobo Aura H2O Edition 2 can meet the Respect Your Freedom certification with an amount of work that is not too big. This page describe research done on the Kobo Aura H2O Edition 2 e-reader. 11 Enabling people to easily install and backup a rootfs.10.3.3 Stock kernel and modules modules.10.2.2.1.1 Getting the kernel configuration and device tree source file name.10.1.4 Adding extra kernel commandline arguments.8.3 Devices described in code but not present on the PCB?.7.2.6 Triggering fastboot without access to the serial port.
