1. to daniel , pls update newest zImage and related CONFIG. i remember i only use boot-usb to download the android 2.6.25, i dont use gen-blob. why? when the battery is quickly insert, at this time the system log will be still in the ram. so use boot_usb to dump the kernel message, but as you say , the boot_usb , gen-blob may flush part mem , right???
anther quesiton , i see there is no much USB UDC code to support usbnet communcation, whether openezx git mainline dont support usbnet so i couldnt use NFS to mount ROOFS. i could only use SD card??????? could you guide me the detail how to port related BSP, steps. for example sdram , fb init, ram console init, bp init, emu etc. 2. whether related dev node will be created dynamicly , such as logger, binder, ashem, fb , these device nodes should be created by hand?? 2009/6/16 Daniel Ribeiro <drw...@gmail.com> > Em Ter, 2009-06-16 às 11:35 +0800, hu zhangli escreveu: > > after i download zImage to A1200 , the lcd panel is confused and > > no kernel message print. could you recommend one way to dump out the > > startup message? > > You can use boot_usb/gen-blob to read the phone RAM after the crash.
