[please keep the cc, thanks] Hi, greg k-h pointed me to this list to ask for help, so here we go: devices ======= Basically every reader with an epaper display from Sipix currently available belongs to this family. Some examples are the Thalia/Medion Oyo, Sagem Binder aka Fnacbook, Asus DR-900, MrBook ONext, Bq Avant, Positivo Alfareader. Should be more than 20 different models sold worldwide. They are based on a Samsung S3C2416, 128MB ram and come with either 6" or 9" display combined with a capacitive touchscreen. Among optional features are wlan chips, gsm modems and accelerometers. status ====== The original u-boot on the devices I've seen so far can dual-boot from either the internal flash or a microsd card. Yesterday we managed to boot 2.6.37rc8 + next-s3c24xx from linux samsung [1] + some patches from a series not yet applied to this branch fixing the second hsmmc channel [2] for the sd card. Access to serial console is known [3], JTAG is not but should be on the same connector. sources ======= The devices originally use a crude fork of kernel 2.6.21.5 with support for s3c chipsets combined with drivers for the addition hardware components. The german vendor Thalia released their u-boot and kernel source on [4]. Still missing is the driver for the AUO-K1900 framebuffer and the MediaTek MT5921 wlan chipset built into some models but I'm hopeful to have this sorted in 2 weeks or earlier. Asus is working on the source release and guessing from my comunication with their gpl compliance officer seemed interested in alternative firmware- developments for their device. components ========== Most of the stuff contains numerous switches for the different submodels made by qisda employees. The following components have code in various quality states: sound: rtl5624 and rtl5627 with s3c2416 integration (sound/soc/codecs and s3c) touchscreen: capacitive and seems to support multitouch (according to sources) made of two Tango S32 controllers combined with an ATmega168PA. drivers/input/touchscreen/s3c_ts_iic.* and drivers/i2c/chips/qisda_iic.c The keypad driver is really strange. It seems to contain the charger logic amongst other stuff. (drivers/input/keyboard/s3c-keypad-qisda.c). Regulator and battery hardware seem to be from TI: BQ24075, TPS650240. A bit of insight into the hardware components can be found on [5]. last words ========== So if anyone more experienced with kernel development could lend us a hand with porting (and cleaning) any of this stuff I would be really grateful.
