T1040RDB_booting from SPI

[vijayb1]

Hi,

We are trying to boot T1040RDB from SPI, here is what i have tried so far

1) Build u-boot.(make T1040RDB_SPIFLASH_defconfig)

    make

2) copy the generated u-boot.bin and u-boot-with-spl-pbl.bin

=>tftp 100000 u-boot-with-spl-pbl.bin

=>sf probe 0

=>sf erase 0 100000

=>sf write 100000 0 $filesize

write u-boot.bin at offset 0x40000 (256KB):

=>tftp 100000 u-boot.bin

=>sf write 100000 40000 $filesize

Change the switch setting as below

SW1 [1:8] = 0010 0010

SW2 [1:8] = 1011 1011

SW3 [1:8] = 1110 0001

So far i have been unsuccessful, my understanding is that u-boot will build PBL.bin with default rcw which is good enough to test boot from spi. Is my understanding correct? Am i missing something?

Thanks

I am able to generate SPI image, and i can boot, my question is more on the serial nor flash memory layout, more specifically on secure boot, where should u-boot header/boot script header should go at what address?

It will be more convenient to support the issue as a Technical Case:

1) Which exactly board is in question - i.e. what is written on the board itself and in on-board sticker(s)?

2) Which version of the NXP Linux SDK is used?

Hi Ufedor

1) T1040RDB Rev B - SCH28125 RevB/700/28215 RevB

2) I am using Linux SDK 2.0

Thanks

> 2) I am using Linux SDK 2.0

The SDK 2.0-1703 is able to generate complete bootable SPI image (it contains RCW, PBL, U-Boot at once - refer to the attached image), but for the T1040D4RDB board - it is possible to refer to the SDK Images ISO available at:

Attached are PBL.bin and u-boot.bin that i am using.

rcw seems to be correct

Below switch settings worked for me

SW1 [1:8] = 0010 0001

SW2 [1:8] = 1011 1011

SW3 [1:8] = 1110 0001

What is the serial nor flash memory map for SPI boot, at what address should we flash kernel image and dtb for spi boot?
