Hello,

I'm trying to port genode onto i.mx53 quick start board. I followed the building steps in this thread. http://sourceforge.net/p/genode/mailman/genode-main/thread/9167aa55bacd5e3f00e64168280aef3e%40lcc.uma.es/#msg31683911

Now i get uImage in in the building directory(var/run/tz_vmm) with other two files (boot_modules.s and image.elf). The size of uImage is 7.5MB

I loaded the uImage to memory address 0x70800000. When I tried to boot with the same memory address (bootm 0x70800000), i get the following error.

## Booting kernel from Legacy Image at 70800000 ...
   Image Name:
   Image Type:   ARM Linux Kernel Image (gzip compressed)
   Data Size:    7858693 Bytes = 7.5 MB
   Load Address: 70010000
   Entry Point: 70010000
   Verifying Checksum ... OK
   Uncompressing Kernel Image ... Error: inflate() returned -5
GUNZIP: uncompress, out-of-mem or overwrite error - must RESET board to recover
resetting ...

I tried again with another memory address (0x78000000) if there was overlap. Still I get the same result.

I also checked if there is overlap with the physical address ranges used by u-boot bootloader using readelf.

Here is the output

Elf file type is EXEC (Executable file)
Entry point 0x70010000
There are 3 program headers, starting at offset 52

Program Headers:

LOAD 0x073000 0x7007b000 0x7007b000 0x0b03c 0xd3ed5 RW 0x8000

What is missing? thanks in advance

best regards,

Joseph,
