Writing bootloader failed

AlekseyM — Fri, 14 Jul 2023 16:24:59 GMT

Hi! I make a custom board with iMX8MM and compile u-boot. But I can't understand what I do wrong. Could somebody tip me?
I use uuu under Windows 10, for compiling images I use imx-boot under WSL2 ubuntu 20.04.

Hi @AlekseyM!

Thank you for contacting NXP Support!

What command are you using under uuu?

If you want to download the bootloader to iMX8, you have to put the board in download mode and then use the next command:

./uuu.exe -b <boot_type> flash.bin

boot_type could be:

emmc

fspi

I attached the UUU guide to understand better the commands that you can use for all iMX devices.

Best Regards!

It seems the flash.bin size + boot offset is bigger than the emmc boot partition size 2M

MMC write: dev # 2, block # 66, count 4086 ... MMC: block number 0x1038 exceeds max(0x1000)

Re: Writing bootloader failed

Chavira — Thu, 20 Jul 2023 13:06:11 GMT

Hi @smithcoba, @AlekseyM!

Can you share with me the steps that are you are following to create the flash.bin, and what commands are using under uuu?

Re: Writing bootloader failed

AlekseyM — Thu, 20 Jul 2023 13:08:53 GMT

I use uuu -v -b emmc flash.bin
also I try use sd-card
uuu -v -b sd flash.bin
emmc 32Gbit
SD-card 8GB

Re: Writing bootloader failed

Chavira — Thu, 20 Jul 2023 13:12:59 GMT

what are the steps that are you are following to create the flash.bin?

Re: Writing bootloader failed

AlekseyM — Fri, 21 Jul 2023 08:54:07 GMT

1. I make changes in spl.c and dts files for imx8mm-ddr4-evk, and added timing.c from ddr-tool, according to my board.

2. https://community.nxp.com/t5/i-MX-Processors/build-imx-boot-image-in-Yocto/m-p/1679794/highlight/true#M208454
I go to this steps, but I use command for imx8mm-ddr4-evk
here:

$ cd uboot-imx $ make clean $ make imx8mm_ddr4_evk_defconfig $ make

and here:

make SOC=iMX8MM flash_ddr4_evk

Re: Writing bootloader failed

Chavira — Thu, 20 Jul 2023 15:20:34 GMT

How are you putting the processor in download mode?

Are you using lpddr4 or ddr4?

If you are using lpddr4 in your board the problem could be that.

If you follow the instructions of the post that are you mentioning is for lpddr4 and you are compiling for ddr4.

In general, I don't see a bad step in all your process but is important to clarify the memory that you are using and compile the correct one.

Re: Writing bootloader failed

AlekseyM — Thu, 20 Jul 2023 16:34:32 GMT

1. I switch the boot mode to sequential boot using the boot0 and boot1 pins.
2. DDR4.
3 What needs to be changed in the instructions for creating flash.bin for ddr4? I changed "make defconfig for ddr4" and imx-boot flash_ddr4_evk.
As far as I can see, the initialization, training, etc. associated with ddr4 or lpddr were successful.

I think the problem is that I didn't change the emmc config in spl, but I don't know where I can change that.
Also, u-boot after the "mmc dev 2" command shows me the correct emmc info.

Hi @AlekseyM !

For your custom board, you have to create our custom DDR training based on your custom board.

Please follow the attached guide to update the ddr training and ddr timing on your board.

Re: Writing bootloader failed

AlekseyM — Fri, 21 Jul 2023 08:51:26 GMT

Yes, of course, I created timing.c from DDR-tool. Without this my ddr4 not initiate.

Here is your log.

Detect USB boot. Will enter fastboot mode!
Starting download of 2091712 bytes
...............
downloading of 2091712 bytes finished

MMC write: dev # 2, block # 66, count 4086 ... MMC: block number 0x1038 exceeds max(0x1000)

The space you must have on boot1:

66 x 512 + 2091712 = 2,125,504

The space on the emmc boot1:

4096 x 512 = 2,097,152

2,097,152 - 2,125,504 = -28,352

The emmc is 32G, it is user partition. not boot partition.

The log shows the boot partition is 2M big. That I have told you before.

If you use scard, the flash.bin can flash into it.

Usually, the NXP binary demo image flash.bin is bigger than 2M.

If you want use the emmc currently on your board, you must change the uboot configuration to make it smaller.

Re: Writing bootloader failed

smithcoba — Fri, 21 Jul 2023 11:07:26 GMT

If the memory(ddr4/lpddr4) type is wrong.

It could flash or not? The flash.bin could run correctly or not?

NXP "expert" answer my question!!!

Re: Writing bootloader failed

Chavira — Fri, 21 Jul 2023 13:18:48 GMT

Hi @smithcoba !

You should not boot or flash the firmware.

The defconfig that are you compiling is for our evk board and has different hardware than your board.

That is the reason that you have to adjust the DDR timings according to your board.

The guide that I attached previously is very helpful and shows how to do all the processes, after that should flash the firmware to your board and boot your board correctly.

Best Regards!

HI @smithcoba!

The problem is not the size of the image, as I mention before the problem is the DDR initialization.
Those binaries were created for our evk you have to create your custom fhash.bin according to the manual that I attached previously.

After that, you should flash your board and boot your board.

Best Regards!

Thanks for your help!

Re: Writing bootloader failed

AlekseyM — Fri, 21 Jul 2023 14:36:29 GMT

Sorry, could you tip me, where I can change boot partition on emmc? in defconfig or another place?

Re: Writing bootloader failed

rudi_cyber — Tue, 25 Jul 2023 02:34:32 GMT

I have the same question.

If the memory type(ddr4/lpddr4) is wrong. It doesn't match the hardware.

The flash.bin can run correctly and run till uboot stage? it stops at ddr training stage or not?

From AlekseyM's log, it runs to u-boot stage. Even starts to flash image.

Here is the log.
