linux is not booting on the zedboard

100aditya over 9 years ago

Hi,

I have done first partition of mine Zedbaord and given it name Boot and i copied following things here:-

BOOT.bin

uEnv.txt

devicetree.dtb

uImage

uramdisk.image.gz

Now i am trying to boot it from SD card but it is not happening and i am getting the following message. In this message i have highlighted the error message specially along with other relevant message that i have got in mine tty terminal.

The content of mine uenv.txt file is as follows:-

boot_Zed=mmcinfo;fatload mmc 0 0x3000000 ${kernel_image}; fatload mmc 0 0x2A00000 ${devicetree_image}; fatload mmc 0 0x2000000 ${ramdisk_image}; bootm 0x3000000 0x2000000 0x2A00000

uenvcmd=run boot_Zed

I have created the ramdiskimage by following command:-

mkimage -A ARM -T ramdisk -C gzip -n 'ZED filesystem' -d ramdisk.image.gz uramdisk.image.gz

Upon execution of above command i got the following message:-

Image Name: ZED filesystem

Created: Mon Oct 24 10:40:13 2016

Image Type: ARM Linux RAMDisk Image (gzip compressed)

Data Size: 18046997 Bytes = 17624.02 kB = 17.21 MB

Load Address: 00000000

Entry Point: 00000000

So based on mine above information please can u please tell/suggest me the solution of mine problem.

Hi Aditya,

I ran into similar problems when we started using larger RAMdisk images on ZedBoard. I found that my problem was related to copying files over the top of each other in memory when U-Boot is loading components from the SD card.

Something similar may be happening to you here, take a look at your RAMdisk image which advertises itself as 18046997 bytes (which is 0x1136015 bytes) long. Since you are loading this to 0x2000000 in memory, it occupies 0x2000000 to 0x3136015 (which is 0x2000000 + 0x1136015) which stomps over the top of your devicetree which you loaded to 0x2A00000 AND over your kernel which you loaded to 0x3000000.

Overwriting either the kernel and devicetree with over data would prevent you from successfully booting Linux. I suggest you go back and evaluate where these Linux components can be loaded into memory so that they do not overlap.

Another alternative to managing all of this on your own would be to switch over to using either Xilinx PetaLinux Tools or Wind River Pulsar Linux to help you get your design up and running faster.

Regards,

Hi Kevin,
First of all thanks for such a great reply as myself would have never figured it out as i am very new to such kind of Linux development environment on SoC boards. I will look into this and come back to u. The addresses that i am using,i have got from http://architechboards-zedboard.readthedocs.org/en/latest/quick.html webpage and also this matches with U-boot/ zed_common.h file. So i thought that it is standard thing.
So what you told seems to me logical also. So i will change the addresses. I have total address 0x20000000 .So one thing that::-
1- is it that , at each address only one byte is stored?????Why i am asking this because from some tutorials i got this thing(may be i understood wrong) that at each address two bytes(16 bit) are stored.
2- So i will change accordingly in mine uenv.txt file , then do i also need to change something in mine U-boot/ zed_common.h(which basically contains the setenv variables definitions at the boot time).
lastely, Nice suggestion by you:- "Another alternative to managing all of this on your own would be to switch over to using either Xilinx PetaLinux Tools or Wind River Pulsar Linux to help you get your design up and running faster."
But right now i am in not in a situation to jump into this. I have posted many questions on this forum and As you can see that i am on this work since last one and half months because i started following the webpage http://zedboard.org/product/wilink-8-adaptor which suggested to me to use http://architechboards-zedboard.readthedocs.org/en/latest/quick.html.That is why i could not use PetaLinux etc and now i have come very far.
Thanks you guys always guiding me and helping me all the time. As i have come so far, so let me try this the last hurdle also.
Please keep on guiding me.

Aditya

Hi Kevin,
Please see mine previous reply against your reply(if seen already it is ok and you can read this now). Then this is the uenv.txt file that have changed as per mine advertised address:-
boot_Zed=mmcinfo;fatload mmc 0 0x3300000 ${kernel_image}; fatload mmc 0 0x3200000 ${devicetree_image}; fatload mmc 0 0x200000 ${ramdisk_image}; bootm 0x3300000 0x2000000 0x3200000
uenvcmd=run boot_Zed
1- So is it ok now??.
2- Now also i have used printenv command to list the setenv variables which is as follows.Please have a quick look and suggest me if anything need to be modified here,since i am going to change mine uenv.txt file. But as per mine thinking since i am using uenv.txt file so in that case nothing need to be modified here.

Hi Kevin,
Please read mine previous reply to u before reading this and if you have alreday read then it is ok. So i have changed mine uEnv.txt filewhich is as follows and as per mine advertised address that you have noticed alreday.
boot_Zed=mmcinfo;fatload mmc 0 0x3300000 ${kernel_image}; fatload mmc 0 0x3200000 ${devicetree_image}; fatload mmc 0 0x200000 ${ramdisk_image}; bootm 0x3300000 0x2000000 0x3200000
uenvcmd=run boot_Zed

1- So it seems to me ok. is it????

2- Also i used the printenv command and list the setenv variables during boot time. Please have a quick look on this and suggest me that any thing that need to be modified here also as i have changed mine uEnv.txt file. But as for as i think it does not need any kind of modification. Am i right????

Hi Kevin,
Actually i have modified mine uEnv.txt file and now that problem has gone but now i am getting kernel panic messsage. Can you please advice for this. Here i am again dumping the serial terminal dump:-
