I.MX6Q Kernel bring up fail with SDCard. what I should do ?

[albatros74]

HI everybody,

I'm trying to bring up with my test board. I have 2 board. one is working well, but other is not.

basic setting ; I.MX6Q, SD Card.

but it has a problem with below message.

I want to know what is problem in this board. 

if you have any idea. please let me know. ( I uploaded working log and error log )

Hi, @albatros74 

>>>HW team remade it ( circuit is the same, but PCB artwork is remaded. some parts changed but specification is almost same)

A : Sorry I don't know the detail PCB remaded, and we do not support PCB review.

Suggest you check whether the new board's PCB design is OK according to the design document I shared with you

[albatros74]

Hi pengyong

device bring up is success. but it has a problem.

I disabled kernel configuration some items.

List: 

"Symmetric multi-processing"
   - allow booting SMP kernel on uniprocessor systems
   - support cpu topology definition

I want to know how to solve or reason.

[albatros74]

Hi pengyong

I solved this issue with HW support. HW team find some power line issue.

Thank you for your support.

[pengyong_zhang]

Hi, @albatros74 

I don't think it is your HW issue, Sorry I can not reproducte your issue on my site.

1. Please use the same SD card, same Image. run on the working old board and new not working borad boot. Do not change any code. Share your Full boot log to me.

2. Your DDR is no problem, otherwise the uboot can not boot.

3. >>>so, they find new part but it is the same clock and specification is almost same.

Please double check only this different between old board with new board?

4. Your PCB design can refer to the attachment.

I don't think it is your HW issue, Sorry I can not reproducte your issue on my site.

1. Please use the same SD card, same Image. run on the working old board and new not working borad boot. Do not change any code. Share your Full boot log to me.

: my board is customized IMX6Q board(DDR/SD/EMMC/IMX6Q core board). HW team  made it with  other company. that is old board.
  old board is working well. but it has some issue about mass product and license. so HW team needs to remake customize board on our own ( other company can't help now)

HW team remade it ( circuit is the same, but PCB artwork is remaded. some parts changed but specification is almost same)

 old board is working well with sdcard and emmc. but new board is not.

 so, I'm finding the reason now.  I don't change sw. I only change someting for testing ( arm freq, bus freq, ddr test ..etc )

  I want to know what it makes this issue. if it is depends on pcb artwork. I will suggeest re-artwork.

  but, if I change some point ( clock / kernel configuration), and it will help to bring up.
  I will talk next action about this. 

2. Your DDR is no problem, otherwise the uboot can not boot.

   : DDR stress test is OK, ( not tested aging but, basic test is no issue)

3. >>>so, they find new part but it is the same clock and specification is almost same.

Please double check only this different between old board with new board?

   : I will check again the difference and update it

4. Your PCB design can refer to the attachment.

   : Thank you so much, I share it to HW, HW team will check.

Hi, @albatros74 

Please add your desired cpu frequency to the imx6q.dtsi file, modified in the following location:

Then run the command on the uboot.

Hi Pengyong

I checked the clock 

changed all low / mid / high.  like below ( example : fix low clock )

but it is not work. so, I'm check the DDR now.

 operating-points = <

                /* kHz    uV */

                396000  975000

                396000  975000

            >;

I think that it is related with PDN ( Power distribution network), 

Did NXP support the PDN simulation ?

if yes, how to request.

if no, Did you have any information of PDN or PCB artwrok reference.

Hi pengyong_zhang

Thank you, I will check it.

Hi, @albatros74 

>>>so, if it is possbile. I want to execute demo version. but I can't find the demo version.

It is to old demo, Now can not find it.

About change cpu frequency, I think the following link can help you. 

one can refer to Chapter 23 CPU Frequency Scaling (CPUFREQ) Driver

attached Linux Manual.

https://community.nxp.com/t5/i-MX-Processors/i-mx6q-cpu-frequency-question/m-p/907442

[albatros74]

Hi Pengyong

I want to change cpu clock but it's not bring up.

so, I can't change cpu clock with command.

so, I need to example code for default bring up setting.

BR

[pengyong_zhang]

Hi, @albatros74 

About change the DDR frequency, you can use the DDR Stress Tool as folllowing link:

https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/i-MX-6-7-Series-DDR-Tool-Release/ta-p/12...

The CPU frquency, 

you can add boot command in the uboot to set it run on different Mhz.

For example : "arm_freq=800"

[albatros74]

Hi Pengyong Zhang

I'm trying to check your comment now. 

and I find the other contenest in this site

https://community.nxp.com/t5/i-MX-Processors/ImX6Q-stall/td-p/319412

out issue and above issue is very similar. HW team will check the voltage.

so, if it is possbile. I want to execute demo version. but I can't find the demo version.

Do you know that version ?

[albatros74]

I tested arm_ freq, but it is the same issue.

I uploaded full log.

Hi, @albatros74 

Yes, you can try fix the clock setting, One question you said "they change Xtal ( 25Mhz, the same) which is a little different but basic clock the same", can you tell about more detail about it, what is Xtal? and what's different between old board and your new board?

[albatros74]

HI Pengyong_Zhang

HW team is checking the xtal parts now. they can't find the same xtal which is used old board.

so, they find new part but it is the same clock and specification is almost same.

I'm trying to find clock setting now. but I'm not farmilar with clock setting.

I only want to change CPU and DDR clock, not other device.

Do you have any information about this?  (I.MX6Q)

bootloader working is good. so, I think that if I changed clock by bootloader, it will work.

( I guess)

Thank you in advance.

@albatros74 

Have you try the latest BSP code?

[albatros74]

@pengyong_zhang

>

I used the same BSP code now. but one is ok, other is not.

I don't know exactly but it is related with clock setting ( I guess)

so, I'm finding the clock setting, I want to fix it ( low clock)

[albatros74]

I explain detail.

Old board : it is working well.

new board : it is not working.

we need to remake main board for some license issue. so we need to make new board. but HW parts and basic components are the same.

HW team said, they change Xtal ( 25Mhz, the same) which is a little different but basic clock the same.

b1.txt : old board and normal bring up log

b2.txt : new board and it is not working and log.

BR

albatros.

[pengyong_zhang]

Hi, @albatros74 

You use two identical boards and the same image, but one board works fine, but the other board doesn't work, Only different is the SD card. right?
