Sorry, i should stop using the 'brick' word loosely. I always use original boot.bin for that reason, and then i know i can always get it back. I just didn't want to have to go to the trouble of doing that so flashed it back while still connected. I meant 'brick' as in 'won't boot' or 'partly bricked' but you might say 'you can't be partly pregnant either' therefore it's either bricked or it's not.

..... If you really want to boot it, you need to wrap fw_all.bin with a special loader which will move it to the right loading address and execute. But there are not such loader, I haven't written it yet.

Umm, you haven't written it YET?? So you can write it. Now would be nice, but ... i suppose you have other more pressing things to do. We can wait, i guess ....
PS: Have you done it yet??

Here is system board of nuvi 3490.

The processor is [Only registered and activated users can see links. ] 800 MHz ARM Cortex-A8 from Texas Instruments. It is very widespread processor in mobile devices.
Below from the processor there is a RAM module [Only registered and activated users can see links. ] from Samsung. This is 1GB (???) MDDR module.

P.S. Special thanks to [Only registered and activated users can see links. ] for device disassembling.

Thanks for the PICS of 3490, Much appreciated.
I've been looking for the schematic, and/OR PINOUT for the 3490 Powered Mount for a while Now. Pictures would also be good.
Maybe you are the right guy to talk to.

None.

..... I was going to create such relocating loader, but then I was stuck with the case when the old firmware location and the new firmware location overlap and with minimizing memory usage, and with the need of compressing the firmware (to allow executing fw_all.bin through copying it to RAM directly by flashing it with RGN instead of boot.bin).
Then I've got a headache, and stopped thinking about this loader.

Only bit i understood was 'Then I've got a headache, and stopped thinking about this loader'. My head hurts just reading the rest, so... take your time. (i'm going to bed now....)

Was a joke.......Really going to bed now.
