Hi,

I intent to use ls1046a-frwy with LSDK 2004. How do I enable /dev/spidev to access a SPI slave device through mikrobus connection?

thanks,

A.B.

Create sdb1 and sdb2 partitions on your SD card and start flex-installer command again.

Hi Pavel,

I was facing the same issue like:

Installing ./build/images/rootfs_lsdk2004_ubuntu_main_arm64_202005202224.tgz to /dev/sdb1, waiting ...

Install ./build/images/rootfs_lsdk2004_ubuntu_main_arm64_202005202224.tgz in /dev/sdb1 [Done]

lsblk: /dev/sdb2: not a block device

I tried your suggestion; It seems to be not working. can you please help me to solve this?

Regards,

Pratik

Test your writing using the following command  host PC under Linux:

sudo dd if=firmware_ls1046afrwy_uboot_sdboot.img  of=/dev/sdb bs=512 seek=8

Hi Pavel.

The 'dd' command writes just fine to the SD device. There is a problem however with the 'flex-installer' script (or other components) under LSDK version 2004.

Usually the following commands are used for writing .img file to SD card for booting:

under u-boot on the LS1046-frwy board:

=> tftp a0000000 firmware_ls1046afrwy_uboot_sdboot.img

=> mmc write a0000000 8 1fff8

 

or on host PC under Linux:

sudo dd if=firmware_ls1046afrwy_uboot_sdboot.img  of=/dev/sdb bs=512 seek=8

 

Do you use similar commands for SD writing?

Have a great day,

Is there problem for using kernel menu?

Is there problem for changing the fsl-ls1012a.dtsi file and kernel building?

There is a problem when installing firmware, boot and root images from the local builds to any SD under LSDK 2004, previous LSDK versions are fine.

Enable spidev using kernel menu:

> Device Drivers

                > SPI support

                               <*>   User mode SPI device driver support 

 

See the following NXP Community for sdpidev definition in .dts file:

Have a great day,

Hi Pavel,

Thank you, that worked in LSDK 1909. I was not able however to deploy the kernel changes successfully using LSDK 2004.

Regards,

A.B.
