Hi,

Thanks for the useful partition informations.
I would like please to ask if I may:
I see different start address in system.img between the scater_gather.txt of mtk file (0x4340000 in the mtk file) (see below) , to the info in cat /proc/dumchar_info , which shows 0x3740000. Which one is correct ?
