How to restore TinyDistro prebuilt image on LS1043ARDB

[dooggy]

Dear NXP support,

I set Virtual banks select SW5[6:4]  to default setting ( 000 Virtual bank 0 ).

When I was trying to Program a New Primary Protected Application (PPA) firmware on LS1043ARDB,

I corrupted vBank0 by mistake.

I followed the step as described by reference guide..

=>tftp 83000000 ppa.itb
=>protect off 64500000 +$filesize
=>erase 64500000 +$filesize
=>cp.b 83000000 64500000 $filesize
=>protect on 64500000 +$filesize
=>cpld reset altbank

After doing that,  I can't  nor_ boot.

U_boot prompt gives me following message.

You can see board boots from vBank 0.

My assumption is that the board was booted from vBank4 when I programed PPA.

If my assumption is right,  writing something at 64000000 when board is in vBank4 , then it is written in vBank0 area.

Am I correct?

Please give me step by step guide  to roll back to tinyDistro.

many thanks,

You are correct, writing something at 64000000 when board is in vBank4 , then it is written in vBank0 area.

Please download the firmware image with the following command.

wget http://www.nxp.com/lgfiles/sdk/lsdk1709/firmware_ls1043ardb_uboot_norboot.img

Please deploy the firmware image on bank0 of NOR flash with the following command.

=>tftp 83000000 firmware_ls1043ardb_uboot_norboot.img
=>protect off 60000000 +$filesize
=>erase 60000000 +$filesize
=>cp.b 83000000 60000000 $filesize
=>protect on 60000000 +$filesize
