We are loading the zImage.initrd file into 0x120000 address and our bootloader looks for an elf file at that address and then copies the kernel into 0x400000 adrress. > After that the boot-loader jumps to that location and the pro-kernel starts uncompressing the kernel into 0x000000. After that it jumps to 0x0. From head_8xx.S, control is transffered to start_kernel by using a rfi instruction. Our kernel crashes at this location. We would like to hear about any such problem faced by any of you and how you solved the problem. > We are downloading our boot-loader into the RAM (at 0x100000) using BDM and we run the boot-loader from there as we are > Not able to write the on-board flash. > All the addresses mentioned above RAM physical address. > Thanx a lot in advance for your help. > --Rajib > > > ------------------------------------------------------------------------ > > **************************Disclaimer************************************************** > > Information contained in this E-MAIL being proprietary to Wipro Limited is 'privileged' > and 'confidential' and intended for use only by the individual or entity to which it is > addressed.
