JohnRama commented 4 years ago

Environment
- LS1028ARDB
  - SD boot
SW
- OpenIL
- master branch
Question
- I would like to update the kernel in the SD card from u-boot. I just followed the instruction of "3.8.3 Updating target images" OpenIL User Manual, However got following error. Would someone please tell me how you guys update the kernel from u-boot ?
What I tried
- Can not download Image

Use another address for storing the image in DDR, for example 0xa0000000 or higher.

setenv autoload off
setenv serverip 192.168.1.1
setenv sd_tftp_boot 'setenv bootargs root=/dev/mmcblk0p2 rootwait rw earlycon=uart8250,0x21c0500 console=ttyS0,115200 cma=256M video=1920x1080-32@60; mmcinfo; fatload mmc 0:1 0x98000000 ls1028a-dp-fw.bin; hdp load 0x98000000 0x2000; dhcp && tftp a0000000 ls1028/fsl-ls1028a-rdb.dtb;tftp a1000000 ls1028/uImage;run qspi_hdploadcmd; bootm a1000000 - a0000000'

The uImage can be generated from the Image.gz using:

mkimage -A arm64 -O linux -T kernel -C gzip -a 0x80080000 -e 0x80080000 -d arch/arm64/boot/Image.gz /srv/tftpboot/ls1028/uImage

and it is much more efficient to transfer that over the network, since it is compressed. However, the Image is faster to load by U-Boot, since it is uncompressed. Depends on the usage pattern that you need to optimize for...

JohnRama commented 4 years ago

Thanks, however I still am having the difficulty.

I tried to download Image to 0xa0000000 and have the same error. So, i guess I need to compress Image with gzip.

Now Question is how can I generate Image.gz with linux build system ?

When trying to change the config of linux kernel, I can not set KERNEL_GZIP. I guess this is because it has the dependency to HAVE_KERNEL_GZIP, and HAVE_KERNEL_GZIP is not select via menuconfig. So, I manually add following line to output/build/linux-OpenIL-v1.8-linux-202005/.config. CONFIG_HAVE_KERNEL_GZIP=y Then, make linux-menuconfig from openil top directory. However HAVE_KERNEL_GZIP is not enabled...

Probably something wrong with my environment... but really appreciated any help here..

So, i guess I need to compress Image with gzip.

No, that's definitely not 'required'. I could transfer an Image file using your command precisely.

Now Question is how can I generate Image.gz with linux build system ?

Uhm, make? Isn't it already available under arch/arm64/boot/Image.gz for you?

vladimiroltean commented 4 years ago

I see the error code, as absurd as it is (0) is given by the server? https://github.com/openil/u-boot/blob/master/net/tftp.c#L565 What TFTP server are you using?

vladimiroltean commented 4 years ago

Ok, so some googling reveals this U-Boot mailing list discussion: http://u-boot.10912.n7.nabble.com/tftp-errors-times-out-on-large-files-td10204.html

the TFTP protocol has a file size limit of 32M unless one of the later RFC versions is followed.

(so compressing the file would help, contrary to my initial thought)

Since I was able to transfer a 35.2 MB file, it means that my tftp server supports these RFC extensions it seems. I am using xinetd as tftp server on ubuntu 20.04.

Thanks Vladimiroltean and sorry for the late response.

I dug a little bit into detail on this. I just want to share my findings.

I'm using atftpd at debian "jessie". As you said, this tftp server returns back to the client with the error message "Undefined error code" when the file exceed 32 MB (512 bytes/block x 65535 blocks), expecting the client to increase block size, more than 512 bytes/block. https://github.com/seveas/atftp/blob/e60ad90917c727b607975c4077b5b4e1bc85b316/tftpd_file.c#L627

I tried with another tftp server, tftpd-hpa, which resulted into the same behavior with atftpd.

I also tried with tftpd, which work for the file more than 32MB. However, checking tftp messages with wireshark revealed that this tftp server does not use larger block size. It just keeps using 512 bytes block and send more than 65535 blocks (which is against tftp protocol).

I would like to update the kernel in the SD card from u-boot.

Here is what I have eventually arrived after a struggle. I just want to share my way.

setenv temp_addr 0xa1000000                     
fatrm mmc 0:1 $bootfile                         
tftp $loadaddr openil/Image.gz;                 
unzip $loadaddr $temp_addr                      
fatwrite mmc 0:1 $temp_addr $bootfile $filesize

Note:

Image.gz can be created by chaining "Kernel image target name" to "Image.gz" from "Image" in openil config.
fatwrite/fatrm is available by enable CONFIG_ENV_IS_IN_FAT in uboot.

Thanks. I'll close this thread.
