raspberrypi4-64: u-boot.bin is too large

[jebr224]

DEBUG: obmc-phosphor-image-1.0-r0 do_generate_static: Compare needed=585520 available=524288 margin=-61232

Raspberrypi use exclusively sd cards (SDXC), so there I would think it is easy to give the u-boot partition the 61 KiB it needs, by moving the kernel offset up. I don't know how many other partitions would need to be adjusted.

Alternatively we could decrease the size of uboot. I don't know how managle an effor that would be.

Hi. Jebr224,
Thank you for your analysis and resolution to this issue.

After I had this issue, I tried older releases and saw what happened to understand a change in which release could cause this. I picked up 2.8.0 release first and made it. I also made sure the 2.8.0 image actually was booted on my Raspberrypi4 platform.
My second choice was 2.7.0 to prove if I happened to make it on 2.8.0. However, I had different issues for 2.7.0 and failed.
Although I wanted to show 2.7.0 and 2.8.0 had no issues related to this "image is too large", I made sure at least 2.8.0 worked without this.

I pasted some of logs below just for Raspberrypi users reference.

Step#1: Git clone 2.8.0 to my local machine.

yocto@yocto-VM:~/Rpi4$ git clone https://github.com/openbmc/openbmc.git -b 2.8.0

Step#2: Set TEMPLATECONF for Raspberrypi.

yocto@yocto-VM:~/Rpi4/openbmc$ export TEMPLATECONF=meta-evb/meta-evb-raspberrypi/conf
yocto@yocto-VM:~/Rpi4/openbmc$ echo $TEMPLATECONF
meta-evb/meta-evb-raspberrypi/conf

Step#3: Set my environment by an openbmc script.

yocto@yocto-VM:~/Rpi4/openbmc$ . openbmc-env 

Step#4: Configure local.conf for my environment.

yocto@yocto-VM:~/Rpi4/openbmc/build/conf$ diff local.conf local.conf.bk 
  1c1
  < MACHINE ??= "raspberrypi4"
  ---
  > MACHINE ??= "raspberrypi"
  18,22d17
  < 
  < DL_DIR ?= "/home/yocto/Yocto/downloads-2"
  < SSTATE_DIR ?= "/home/yocto/Yocto/sstate-cache-2"
  < IMAGE_FSTYPES += " rpi-sdimg"

Step#5: Configure FLASH_SIZE for my environment.

yocto@yocto-VM:~/Rpi4/openbmc/meta-phosphor/classes$ diff image_types_phosphor.bbclass image_types_phosphor.bbclass.bk 
  38c38
  < FLASH_SIZE ?= "131072"   <<<  FLASH_SIZE is changed from 32768 to 131072.
  ---
  > FLASH_SIZE ?= "32768"

Step#6: Start bitbake

yocto@yocto-VM:~/Rpi4/openbmc/build$ bitbake obmc-phosphor-image

  Snip the log and left the important logs here.

Hi Student2C0, i want to cpmpile openbmc for my raspberry 4B but i get lots of error , could i get your version about your environment? like python version ,etc. thank you

[Student2C0]

Hi caohj1996,
I built my openbmc Rpi-image a year ago. So, I am not sure if this could help you but I share my information with you below.

#1: HW environment
Rpi-4B

#2: Open BMC Release
2.9.0 and 2.8.0
I could build both releases.

#3: Python pkg
Please see the following output.
I remembered I got a few errors related to some pkg and they all needed other pkg to build the image.
You could find what you needed in build logs when you hit the error.

#4: Solution for u-boot.bin is too large
I did a lot of tries and found out what the root cause was. The partition of file system has pre-defined format like below.
Rpi image does not fit into these pre-defined sizes and you need to tweak each size to accommodate your image into the partition.
The following is what I did for my image. You change the size of u-boot. Then, the partition next to it fails due to lack of its size.
So, you change each size to accommodate all partitions. This may not work for the device with limited memory size like 32MB since we can not extend the size beyond its capacity but it worked for Rpi.

#4: Solution for u-boot.bin is too large I did a lot of tries and found out what the root cause was. The partition of file system has pre-defined format like below. Rpi image does not fit into these pre-defined sizes and you need to tweak each size to accommodate your image into the partition. The following is what I did for my image. You change the size of u-boot. Then, the partition next to it fails due to lack of its size. So, you change each size to accommodate all partitions. This may not work for the device with limited memory size like 32MB since we can not extend the size beyond its capacity but it worked for Rpi.
