[LS1028A] : Unable to boot u-boot from FlexSPI flash

[Arathi]

Hi @nxp support Team,

We are working with NXP LS1028A processor connected to 32 bit DDR4 + 4bit ECC(MT40A1G16KH-062E) and FlexSPI NOR Flash (MT35XU01GBBA1G12).

In JTAG mode I am able to connect to code warrior Flash prompt and load the generated images into NOR flash as shown below

When i am trying to boot from NOR Flash it is getting stuk after bl31 phase with the print NOTICE: Welcome to LS1028 BL31 Phase

I able to connect to DDR validation tool of CodeWarrior Development studio. Tried running validation and operation test for DDR4 with 800MHz speed and found both to be passed. Configured the generated DDR config parameters into uboot ddr_init.c file in the path packages/firmware/atf/plat/nxp/soc-ls1028/ls1028ardb/ddr_init.c .

Attaching the generated ddr config file for your reference

still observed the uboot to get stuck after bl31 phase.

Pls do help us to boot LS1028A from NOR flash and let us know what else has to be done for the same.

Thanks and Regards,
Arathi
