Tool/software: Linux

Hii All,

Can anyone let me know how to bring up Linux zImage from QSPI in AM5718 IDK ?

I have followed the following link to bring up u-boot from QSPI successfully.

I am replacing uImage with zImage and using bootz ${loadaddr} - ${fdtaddr} command to get Linux.

My booting log is :

Hello Arpita,

Could you please confirm if you are trying to boot kernel/file system from eMMC or QSPI? Also, if you are booting from QSPI, I am wondering if you could please share the size of your flash memory.

Krunal

Hello Krunal ,

I am booting it from QSPI . I have booted u-boot and not able to boot Kernel/ file system.

Flash Memory Size is 256Mb (32768 Kbytes).

Hi Arpita,

Could you please confirm if your filesystem is small enough to boot the system and fit inside the Flash Memory?

Hi Krunal,

After trying with different rootfs, I realized that the rootfs I'm using is large enough not to fit inside the flash memory.

Thanks for the response.

Is is possible to bring up u-boot from Flash and linux and rootfs from SD card ?

What changes I need to do to achieve the same ??

Thanks and Regards...

Hi Arpita,

I believe that should be possible and based on your earlier logs, it seems like you board booted from QSPI and is looking for the FS/kernel from the SD card.
