hello all!
can anyone help me with the subj? I've tride to dump ROM (128MB) with grab_it and fizifetch. their results are identical. but there is repeated text blocks (beginning system initialisation etc...), so I'm not shure, is my dump correct. first 1MB of dump attached. how to check if the dump correct or not?

how to disasm bootloader (first 256kb?) can anyone explain to me? what parameters I need to set in IDA, what offset is an entry point (zero, I think), how bootloader checks for pressed keys? I need this, cause I want to find magic key combinations (testmenu, flash util, etc..)

1. The image does contain bootloader code
2. Entry point is 0x1000

thank you, ady
can you tell me, how to determine that some keys combination is pressed? how reading of keycodes in arm pda's processed on the low level? what registers, addresses, ports, etc. is used?.....
