How to boot LS1088A from spi nor flash

Jackie19 — Thu, 02 Oct 2025 04:29:06 GMT

Dear NXP support,
I am developing my ls1088a board based on the LS1088ARDB.
My board worked if boot from sdcard. So, I want to boot from nor flash.
I followed the link: https://community.nxp.com/t5/Layerscape-Knowledge-Base/LS1088ARDB-LS1088ARDB-PB-How-to-update-composite-firmware-image/ta-p/1103848 by the steps:
1. Download composite firmware
2. Built-in the composite firmware into firmware that was flashed to sdcard
3. Boot my board from sdcard and enter the u-boot
4. In u-boot console, load composite firmware from sdcard to nor flash 0
5. Change switches to select boot the board from QSPI. But it has not any boot log in minicom, ...

Please help me verify the above steps.

Best Regards

Hi Oswalag,

After step 5, I can't see any log.
Do you have an idea to debug this issue?

Thanks

Hi Oswalag,

I resolved the problem by using the kernel 5.15.
As I understand it, the reason is that the first blocks on my spi nor flash chip have a size of 32KB, while if using the erasing command on the old 5.4 kernel, it only supports erasing blocks of size 256KB.

Thanks,
