Rockbox Ports are now being developed for various digital audio players!
Do you, by chance, know if the GSL-2801A is a ChinaChip DAP?http://gslltd.manufacturer.globalsources.com/si/6008827347504/pdtl/Flash-portable/1009251153/Flash-Portable-Media-Player.htm
Hi mcuelenaere and all !I do have a new Onda VX747+ since a week, which I acquired knowing I could start hack it out of the box, thanks to your work and to rockbox team !I could run the bootloader build on the device like a charm, I only had to comment the storage_init function to build it. The lcd and touchscreen are working, but only the vol_down and off buttons where working.I could easily find out with the bootloader the GPIO config, and I made a patch adding a model in rockbox, with buttons working.I just added this patch to the tracker, but maybe adding a new model is overkill, could it be done only with #ifdefs ?The GPIO config is:#define BTN_HOLD (1 << 22) /* on GPIO 2 */#define BTN_MENU (1 << 20)#define BTN_VOL_UP (1 << 19)should I just update the vx747 page on the wiki ?
Hi !Thanks for including it this fast, I just went to sleep and as I woke up you included, like in a dream And the code duplication is gone now, nice I'll continue to test the ingenic code now, as I understand it the current only way is to modify the bootloader code, am I right ?
I just opened an account on the wiki but am still denied editing, when it's OK I'll add gpio config for vx747+.
hello am new the forum. am interested in help porting rockbox on vx747. i have hardware and knowledge on processors. i have player with me and able to upload bootloader. has anyone able to upload rockbox yet? the stable release code base is not fully compile the code for Normal mode. on forum i found that someone was able to play audio, but garbage. where is that code base?thanksjaining

Thank you for quick reply. I hope to use the code after u comitt to the SVN. please reply when u do.For storage, i look at wiki page, shows that FLT not known yet. But that is needed only if we want to run both original FW of player as well as rockbox. what if we format the flash with known FS like FAT, and run only rockbox? please tell if i miss something here.thanks

I committed a working USB driver (receiving data on the device is a bit flaky) and an AFAICS working NAND driver.
hi mcuelenaere, do u have app.lds file for vx747? it is missing from tree.
