Hello!
I've got a Senao ESR-9752 device based on RT3050 and was lucky to find the support for this chip in WHR-G300N firmware. Almost everything works perfectly with provided patches except for the wireless. As soon as ra0 interface is getting up with ifconfig the kernel panics. Is it possible to find rt2860v2_ap and rt2860v2_sta modules for kernel 2.6.23.17 for this chipset somewhere in sources or binary. Your help would be appreciated.

i have a working firmware for this device. the problem is that the original bootloader has a bug and does not allow to install firmware bigger than 4 mb, even if the device has a 8 mb flash memory.
the unit has no rt3052 ralink cpu, but a rt2880 _________________ "So you tried to use the computer and it started smoking? Sounds like a Mac to me.." - Louis Rossmann https://www.youtube.com/watch?v=eL_5YDRWqGE&t=60s

Sorry for the typo, I wanted to mention ESR-9753, which is based on rt3050(1T1R). Is there any chance to get working firmware or wireless modules for it? I assembled a firmware based on DD-WRT svn sources and kernel for WHR-G300N. Everything is fine, except wi-fi. I think this is because rt3052 and rt3050 are a little different.

did you install the correct firmware files into /etc/wlan? _________________ "So you tried to use the computer and it started smoking? Sounds like a Mac to me.." - Louis Rossmann https://www.youtube.com/watch?v=eL_5YDRWqGE&t=60s

i know just 3 reasons for this.
first. wireless firmware file cannot be loaded, (the path is hardcoded in the driver)
second, the wireless config cannot be loaded from the right path (again, path is hardcoded in the driver)
and the third. the wirelass base config cannot be loaded (stored in the third eraseblock in flash memory)
so driver accesses alot of things and if one fails, it crashes. the access to the flash memory is done by the ralink flash driver within the kernel. this is maybe a point where you can start debugging _________________ "So you tried to use the computer and it started smoking?

I have checked all paths and offsets in flash memory. In drivers/flash/flash_main.c I inserted printk in functions FlashRead() and FlashWrite(),but them does not reach at all.

they must be compiled for each model. _________________ "So you tried to use the computer and it started smoking? Sounds like a Mac to me.." - Louis Rossmann https://www.youtube.com/watch?v=eL_5YDRWqGE&t=60s

the only difference between both devices is the filename of the firmware binary to load. so you simply need to rename it
but anyway. i attached the modules with changed config _________________ "So you tried to use the computer and it started smoking? Sounds like a Mac to me.." - Louis Rossmann https://www.youtube.com/watch?v=eL_5YDRWqGE&t=60s

then the problem is likelly just in the flash driver. _________________ "So you tried to use the computer and it started smoking? Sounds like a Mac to me.." - Louis Rossmann https://www.youtube.com/watch?v=eL_5YDRWqGE&t=60s
Without the source code probably will not solve....
