Building Custom Yocto Image for Mangoh Red WP76

prabjotdhillon · October 22, 2020, 5:48pm

Gotcha. Are the warnings of any concern? Also what is the command to flash the new image to an SD card? Thanks!

jyijyi · October 22, 2020, 11:04pm

No concern for the warning as far as you can build the required .cwe file.

// to mount SD card
mkdir -p /tmp/sdcard
/bin/mount -t auto -o sync /dev/mmcblk0p1 “/tmp/sdcard”

and then you can copy the file to SD card.

prabjotdhillon · October 29, 2020, 6:41pm

Thanks!

I followed the steps you mentioned and copied the .cwe file to the SD card.
However, I could not boot from the SD card after inserting into the board.
Are there any steps that I am missing?

Also,
After adding packages and building the image I receive the following error:
ERROR: mdm9x28-image-minimal-1.0-r0.0 do_image_complete: Function failed: prepare_ubi (log file is located at /home/aswsim/Desktop/Legato-Dist-Source-mdm9x28-SWI9X07Y_02.37.07.00/yocto/build_bin/tmp/work/swi_mdm9x28_wp-poky-linux-gnueabi/mdm9x28-image-minimal/1.0-r0.0/temp/log.do_image_complete.32358)

I have changed the ubi size using various values:
./meta-swi/meta-swi-mdm9x28/conf/machine/swi-mdm9x28.conf
change UBI_ROOTFS_SIZE ?= “48MiB”

But still receive the error

jyijyi · October 30, 2020, 12:06am

You cannot boot from sd card, you need to update the FW by fwupdate command

jyijyi · October 30, 2020, 12:07am

Seems you have put too much recipes to the image…

prabjotdhillon · October 30, 2020, 5:02pm

So I reduced the amount of packages added to the image to just python3 and dpkg but still exceeds the limit … is there a way to increase the volume size? Thanks!

jyijyi · October 31, 2020, 12:15am

New module with fw R16 freshly come out from sierra factory should have bigger size.

You can also see this doc and see if you can run the python in ram area instead of building to the image.

prabjotdhillon · November 5, 2020, 10:10pm

So I downloaded and added python3 and dpkg .bb files and made the required changes in the other 2 files.

When I run make I receive the following error:

prabjotdhillon · November 5, 2020, 10:14pm

Also can i rebuild yocto kernel to enable etx4, that way I can setup debian environment on a SD card that would include python, dpkg packages …

jyijyi · November 6, 2020, 4:58am

You can follow the steps below to run python3:

download the yocto source and go to ./meta-swi/meta-swi-mdm9x28/recipes-core/images/mdm9x28-image.inc
add the following line:
IMAGE_INSTALL_append = " python3"
go to ./meta-swi/meta-swi-mdm9x28/conf/machine/swi-mdm9x28.conf
change UBI_ROOTFS_SIZE ?= “48MiB”
Make the yocto image ( there will be error to make the image, but we can build the binary of python3)
on PC, type :
sudo ifconfig usb0 192.168.2.3
on module, type :

mkdir /tmp/tmp_usr_bin/;mkdir /tmp/tmp_usr_bin_wr;

To use dpkg recipe, you can try the following:

download the yocto source and go to ./meta-swi/meta-swi-mdm9x28/recipes-core/images/mdm9x28-image.inc
add the following line:
IMAGE_INSTALL_append = " dpkg"
type “make” to build the yocto image

prabjotdhillon · November 10, 2020, 7:50pm

the command right before step 8 gives an error: scp ./Legato-Dist-Source-mdm9x28-SWI9X07Y_02.37.07.00/yocto/build_bin/tmp/work/armv7a-neon-poky-linux-gnueabi/python3/3.5.5-r1.0/image/usr/lib/python3.5/*.py root@192.168.2.2:/usr/lib/python3.5
scp: /usr/lib/python3.5: No such file or directory

dont undertand why because the previous command worked but not the command above:
aswsim@aswsim-Precision-Tower-3620:~/Desktop$ scp -r ./Legato-Dist-Source-mdm9x28-SWI9X07Y_02.37.07.00/yocto/build_bin/tmp/work/armv7a-neon-poky-linux-gnueabi/python3/3.5.5-r1.0/image/usr/lib/python3.5/encodings root@192.168.2.2:/usr/lib/python3.5
scp: /usr/lib/python3.5: Read-only file system

jyijyi · November 10, 2020, 11:09pm

Did you do the following?

mkdir /tmp/tmp_usr_lib/;mkdir /tmp/tmp_usr_lib_wr;
cp -rf /usr/lib/* /tmp/tmp_usr_lib/
mount -t overlay overlay /usr/lib -o lowerdir=/usr/lib,upperdir=/tmp/tmp_usr_lib,workdir=/tmp/tmp_usr_lib_wr;

mkdir /usr/lib/python3.5

pawelkaniewski · November 13, 2020, 11:29am

Is there actually a new wp76 module version? Or just a new fw version?

jyijyi · November 13, 2020, 11:49am

I think just new fw with partition size changed.
You can contact distributor for more information

prabjotdhillon · November 19, 2020, 11:01pm

Yes still getting the same error unfortunately

This should be one line command which enter in module console, not your pc:

mount -t overlay overlay /usr/lib -o lowerdir=/usr/lib,upperdir=/tmp/tmp_usr_lib,workdir=/tmp/tmp_usr_lib_wr;

prabjotdhillon · November 21, 2020, 12:43am

Can I resize the partition size? Ideally we would like to fit the image onto the SD card

jyijyi · November 21, 2020, 12:46am

This can only be done by sierra internally, you need to contact distributor.

You can also put those python library in sd card
