T1024RDB boot from sd card

rdk — Sat, 04 Apr 2020 13:00:58 GMT

Hi,

I have accidently brick my T1024RDB NOR flash and so I'm trying to recover it since it is not able to boot anymore.

My question is how to correctly create a SD card and set the switches on the board in order to have the CPU boot from the SD card.

I'm using QorIQ SDK v2.0-1703 and I have try the following procedure :

Copy the u-boot binary (u-boot-sdcard.bin) on the sd with dd command (dd if=u-boot-sdcard.bin of=/dev/sdc seek=8 bs=512).
Copy the FMan micro code on the sd with dd command (dd if=fsl_fman_ucode_t1024_r1.0_106_4_18.bin of=/dev/sdc seek=2080 bs=512).
Copy the QE engine micro code on the sd with dd command (dd if=iram_Type_A_T1024_r1.0.bin of=/dev/sdc seek=2336 bs=512).

Note the descriptor of my sd card is /dev/sdc on my linux station.

I have set the switches of the board to the following position :

Switches	1	2	3	4	5	6	7	8
SW1	ON	ON	OFF	ON	ON	ON	ON	ON
SW2	ON	ON	OFF	OFF	OFF	OFF	OFF	OFF
SW3	ON	OFF	OFF	ON	ON	ON	ON	OFF

With the above settings the CPU does not boot, I have no activity on the terminal port.

I would like to have any hints or advise.

Thanks in advance,

Renaud De Koninck

Described steps are correct.

Please confirm that "u-boot-sdcard.bin" is actually "u-boot-sdcard-2016.01+fslgit-r0.bin" from the "QorIQ Linux SDK v2.0 PPC64E5500 IMAGE.iso".

Hi Ufedor,

Thanks for the reply I have tried booth u-boot binaries, a generate u-boot from the SDK-2.0 sources and the u-boot-sdcard-2016.01+fslgit-r0.bin from the QorIQ Linux SDK v2.0 PPC64E5500 IMAGE.iso.

Actually both are now working, I made an error in the SW1 configuration that was not as described in my post.

Anyway thanks you for your confirmation about the correctness of the steps.

Regards,

Renaud

Hello ufedor‌
Is this method also valid for on-board eMMC with same switch settings ? Our custom design have two options to boot ( nor flash / on-board eMMC) and I want to boot using eMMC.

T1024 can boot from eMMC.

Which exactly settings to use depends on the custom board design.

On T1042 Demo board, I did exactly the same steps mentioned in this question, and board stucked at this screen. Do you have any suggestion about this error. I used SDK V2.0 - 1703 yocto generated 'u-boot-sdcard-2016.09-fslgit+r0.bin' and 'fsl_fman_ucode_t1040_r1.1_106_4_18.bin'.

I double checked switch settings, thet are correct.

Switches	1	2	3	4	5	6	7	8
SW1	ON	ON	OFF	ON	ON	ON	ON	ON
SW2	ON	ON	OFF	OFF	OFF	OFF	OFF	OFF
SW3	ON	OFF	OFF	ON	ON	ON	ON	OFF

Switches	1	2	3	4	5	6	7	8
SW1	ON	ON	OFF	ON	ON	ON	ON	ON
SW2	ON	ON	OFF	OFF	OFF	OFF	OFF	OFF
SW3	ON	OFF	OFF	ON	ON	ON	ON	OFF

Switches	1	2	3	4	5	6	7	8
SW1	ON	ON	OFF	ON	ON	ON	ON	ON
SW2	ON	ON	OFF	OFF	OFF	OFF	OFF	OFF
SW3	ON	OFF	OFF	ON	ON	ON	ON	OFF
