Again thanks for your reply , the board we are using is Nitrogen 6X ,now the size of our uncompressed file is 4.2MB and compressed is 1.8 MB , the RAM base address of our board is 0x10000000 and RAM size is 0x40000000 , we tried booting by assigning load address as 0x10001000 and the entry point as 10001000 and tftp 0x10800000 . We are stuck at starting kernel

Bytes transferred = 1829585 (1bead1 hex)

U-Boot > bootm ## Booting kernel from Legacy Image at 10800000 ... Image Name: Image Type: ARM Linux Kernel Image (gzip compressed) Data Size: 1829521 Bytes = 1.7 MiB Load Address: 10001000 Entry Point: 10005d70 Verifying Checksum ... OK Uncompressing Kernel Image ... OK

Starting kernel ...

Any Idea what the problem is ?

Hi thanks for the reply,I am Archie working with Aditya on this . We use your reprository and then followed the steps given in https://github.com/genodelabs/genode/commit/ce58a63fb661df42e6bf283891589b11... ,https://github.com/genodelabs/genode/commit/ce58a63fb661df42e6bf283891589b11a1f411f2#commitcomment-2891606for creating uImage .

And then booted using tftp with this.

# either 'dhcp' or 'setenv ipaddr xxx.xxx.xxx.xxx' # 'setenv serverip xxx.xxx.xxx.xxx' as long it isn't set via DHCP # 'tftp 0x70800000 [path_to_uimage]/uImage' # 'bootm 0x70800000'

Now the error we are getting in this is

Using FEC device TFTP from server 10.6.1.123; our IP address is 10.6.1.122 Filename 'uImage'. Load address: 0x10800000 Loading: ################################################################# ################################################################# ################################################################# ################################################################# ################################################################# ################################# done Bytes transferred = 1829585 (1bead1 hex) U-Boot > bootm ## Booting kernel from Legacy Image at 10800000 ...

Any Ideas where we might be going wrong?

Hello, Archie

Which type of i.MX6 board are you using? The load address 0x70140000 of your boot image assumes that your board supports 2 GB of RAM (physical address range 0x10000000 to 0x8FFFFFFF). AFAIK not all i.MX6 boards have that much memory, others come with 1 GB instead (physical address range 0x10000000 to 0x4FFFFFFF). In that case you have to modify the build scripts so that the löad address is set to 0x40140000 and the entry point to 0x4018b33c (or other values which fit into the 1 GB range).
