boot i.MX7 via SDP

[sebastian_sedlm]

Hi,
I try to boot the i.MX 7 Dual SABRE Board from my Raspberry Pi via uuu. I followed the steps from the guide. So far it works, until the point where the new Image L4.14.78... should boot to the board.
The Terminal says: Wait for Known USB Device Appear - Prep 1/0.
But when i turn on the board it boots from the sd Card. So it seems, that the Boot configuration is not working. I`ve tried it several times but it`s always booting from the sd Card.
when i remove the sd card, there is no output over the serial port.

And even then nothing happens in the Terminal.
Where is the mistake?

Hi Sebastian

uuu tool is designed for programming images to some media, not

running images. One can look at presentation describing its usage

i.MX 8 Universal Update Utility (UUU) Tools and Pins Tool 

https://github.com/NXPmicro/mfgtools/releases/download/uuu_1.3.154/UUU.pdf 

GitHub - NXPmicro/mfgtools: Freescale/NXP I.MX Chip image deploy tools.

Hi igor, 

first of all thanks for your quick response and sorry for my late reply.

I misspoke, that's my goal as well.
I'm one step ahead. Meanwhile it will react as long as no bootable sd card is inserted.

I am connected to the board via port J11 and J25. I open the cmd and PuTTY.

In the Terminal i enter the following:

chmod a+x uuu

sudo /uuu L4.14.78_1.0.0_ga_images_MX7DSABRESD.zip

Then i turn on the board.

The Terminal fails at 1:14  3/7 [] FB: ucmd mmc dev$emmc_d

Putty gives me the following:

I edited the putty output with a text camera scanner. If the information content is not sufficient I can also copy the identical output.

Thanks a lot for your time and effort.

Hi Igor,

These are the documents I followed. 

But what hint gives me "Card did not respond to voltage select" I don't know how to handle this.

As I have read, often the cable is the problem. But I use the enclosed one.

Best regards 

Sebastian

Hi Igor,

i installed Ubuntu 19.10 via Virtualbox and tried again.

Unfortunately the Error is exact the same: Card did not respond to voltage select.

Hi Sebastian

please try other card and use Demo Image:

Linux Binary Demo Files - i.MX 6UltraLite, i.MX 6ULL, i.MX 7Dual

Just for test please try procedure described in sect.4.3.2 Copying the full SD card image

attached Linux Guide, to check if it works,
 

Best regards

igor

unfortunately I was not able to find a solution for the problem, should someone have the same problem. I solved the problem for me by copying the image over dd.
Anyway, thanks for your help igorpadykov‌

Best regards 

Sebastian
