Stuck at starting kernel...

Hello,

 

I know this is a really noob-like question.

 

But yes indeed my kernel hangs at starting kernel... This happend suddenly cause before it was working then i made my rootfs size bigger and it stopped.

 

My partitions

Name         ADDR    SIZE

BOOT.BIN 0x0  0x600000

uImage 0x620000 0x400000

system.dtb 0x1020000 0x50000

uramdisk.image.gz 0x1070000 0x2000000

POC.bit 0x3070000 0x200000

 

To clarify; the POC.bit is my bitstream. I cheated this in in the QSPIboot configuration in zynq-common.h in u-boot-xlnx to fpga loadb it into the system. Back then this worked cause when I would add it into the BOOT.BIN it wouldn't work so this was my work-around. 

 

Now when I updated to this partitions, WITH THE SAME FILES, it stopped working and also the fpga loadb did not work anymore. I don´t think (yes i'm sorry i think, a lot happened in the meanwhile.) I changed any configurations. 

 

Also to say the filesystem is made with buildroot but this has never given any problems.

 

I will include my zynq-zc702.dts, if you guys need anything else just ask me :) I hope someone knows why this is happening. Also I did first look in 100 posts to find my solution but also because I had this once before and then I actually did find the answer there I find this one so strange.

 

The last thing is that I know my partitions are wrong but that is because I modified zynq-common.h to work. I also included that file, I changed the qspiboot= part and also the addresses and sizes of the different components.

 

Greetings,

Senkoo

Here is the device tree, it kept giving errors.

Re: Stuck at starting kernel...

Hello again,

 

I've tried another uImage I made in the past and this one hangs at the following:

 

IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
mmcblk0: mmc0:0001 HAG2e 14.7 GiB
mmcblk0boot0: mmc0:0001 HAG2e partition 1 4.00 MiB
Initializing random number generator... mmcblk0boot1: mmc0:0001 HAG2e partition 2 4.00 MiB
mmcblk0rpmb: mmc0:0001 HAG2e partition 3 4.00 MiB
 mmcblk0:
PuTTYPuTTYPuTTYPuTTYdone.
Starting CAN
Starting network:

I don't know why...

Re: Stuck at starting kernel...

Hi @senkoo

 

If you think rootfs size is bigger and is greater than 128 MB, you can make below changes to petalinux project:

1. Mention the Bootm length in platform-top.h #define CONFIG_SYS_BOOTM_LEN

2. Undef the CONFIG_SYS_BOOTMAPSZ in platform-top.h

Re: Stuck at starting kernel...

Hi @shabbirk,

 

The size of my uramdisk.image.gz is 14,0 MB so I don't think I'll need to worry about it being bigger or greater then 128MB.

 

Thanks for your response :)

 

Greetings,

Senkoo
