Hi All,
I’m testing L4re on a customized I.MX6 Solo-X-4 board. I found that the fiasco kernel (the simple hello world example built into an uimage) cannot be load by the U-boot. It shows “data abort". The reason I guess it is due to different loading address. The U-boot’s default $loadaddr is 0x80800000, but the uimage I build using the L4re buildsystem has:
Load Address: 11000000 Entry Point: 11000000 ==> Installing bootstrap.uimage in image directory Image size(s) in bytes: bootstrap_hello-cfg.elf: 1470844 bootstrap.raw: 1437696 bootstrap.uimage: 1437760 Start address: 0x11000000
I used the RAM_BASE=0x8080000 option to change the starting address when I made the image (as shown below), the boot did not crash but the kernel hangs at “Starting kernel..."
Load Address: 01000000 Entry Point: 01000000 ==> Installing bootstrap.uimage in image directory Image size(s) in bytes: bootstrap_hello-cfg.elf: 1470844 bootstrap.raw: 1437696 bootstrap.uimage: 1437760 Start address: 0x801000000
I think it is still related to the different load address. But I do not know how to fix it. I would really appreciate if someone can point me to a right direction.
Thanks -Dan
