@Celem Well, you got him to follow simple instructions from the first page finally ::)

If you want to walk him through finding out what hardware he has, that will be fun.


Suggest try flash the kernel file from Kaicom firmware folder, and a romfs from one of the 2M filesystems

The newest camera's have Pixart PAP7501V sensors and RT3070 wifi.
If yours is an older model, then SunPix sensor and vt6656 wifi possibly, or rt73 wifi.

I guess I should roll out a linux + romfs that outputs some debugging info so that we can find that out.

this makes ipcam bought it about 3 months and has wifi.

Ram & cpu good. Flash suspect

Lawrence (admin) just proposed a good solution to possibly salvage your camera - namely using firmware intended for a 2MB flash. In this way, if the flash area is in higher memory, your camera would still work - if the sensor is compatible.

ok, just do not know even how. rs

Lawrence, I enjoy solving crossword puzzles - do them every day. Maybe a connection?

casbeto, Lawrence is suggesting to load the 2MB firmware at:

The sensor is unlikely to be correct, but if it will load and run (at the console) it would prove that your flash's upper memory was bad.

ok, but I have to use what command?
 mx ou fx ?

Follow the notes at that link, but the sequence is probably:
Code: [Select]
fx 7 0x7F020000 0x8000 -acxz
fx 6 romfs.img 0x7F0E0000 0x7F0E0000 -a
fx 8 webui.bin 0x7f180000 0x7f180000 -a

Good luck

set -ip0

Can we change the MAC Address with this or similar command or does it need reflash of Image 0. I have cameras which have all the same MAC.

ok, found it myself it is set -mac0 [addr]

the set command is not accepted!

1. Your camera can correctly install and run a linux kernel and romfs directly to RAM.
2. All actions involving FLASH appear to fail.
3. The ls command shows "BOOT INFO" as mounted yet subsequent accesses indicate that it is corrupted.
4. Conclusion: your FLASH has a problem.

My final recommendation. If this fails, consider the camera a source of spare parts.

Using the bootinfo file previously posted:
enter the following commands:

DEL -all
DEL b1
fx 0 "BOOT INFO" 0x7F010000 0x7F010000 -f   (NOTE: on your PC xmodem send the bootinfo file referenced above)

maybe only the fx command is broken, it would be worth trying to flash via tftp

I will perform the tests, and the night stand for you to see!

 Thank you all!
