I'm testing a SD/MMC manufacture boot flow with MCIMX6ULL-EVK.
In my understanding, when I set SW602 to ON, OFF and witch SW601 to OFF, OFF, ON, OFF without microSD card, I can test a following flow.
However, it seems that it's not into USB download mode.
My confirmation way is using MFGTool.
When I tested with MFGTool, the MFGTool windows shows "No Device Connected”.
So I judged it's not in USB download mode.
On the other hand, I tested same way with MCIMX7SABRE.
It can detect a device.
With a above result, something is wrong with SD/MMC manufacture boot flow for i.MX6ULL.
Is there any information about the error of SD/MMC manufacture boot flow for i.MX6ULL ?
Or please tell me how to check the SD/MMC manufacture boot flow for i.MX6ULL.
Hi Joan Xie
I know that I need to set sw602 to D1=OFF D2=ON when it goes USB download mode.
As I say, I want to test SD/MMC manufacture boot flow, especially, it shows in the figure which is attached in this thread.
In that case, user set BOOT_MODE to "10” first.
Then if the primary boot fail, it goes to the process which it's shown in the figure.
Finally, it goes to USB download mode.
I want to make same situation which is failed in primary boot, so I powered on without insert SD card.
Because I believe that it goes to the flow which I shown in the figure when it failed a primary boot.
Am I wrong ?
If I'm wrong, please show me how to test a SD/MMC manufacture boot flow.
sorry for my delay, I'm out of office this week, I found you've already submit the familiar question in community, any difference?
any update I will check when I'm back to office ASAP
Hi Joan Xie
Thank you for reply.
Let me confirm about my following understanding is correct or not.
I checked a MCIMX6ULL-EVK-DESIGNFILES/MCIMX6ULL_CM_DESIGNFILES/Schematics/SPF-29364_a.pdf and found that the board is not use SD2_CD_B.
From the following answer, Pad of SDx_CD_B is needed to detect whether a card is inserted or not.
However, MCIMX6ULL-EVK is not use SDx_CD_B.
As a result, MCIMX6ULL-EVK can't detect whether a card is inserted or not and can't tested the SD/MMC manufacture mode.
Am I correct ?
sorry for my delay, I tested this for you on my IMX6ULL evk board, when I set SW602 to OFF, ON and witch SW601 to OFF, OFF, ON, OFF with MicorSD card, I can detect the board by mfgtool. then I set SW602 to ON, OFF and witch SW601 to OFF, OFF, ON, OFF without MicroSD card, I still can detect the board by mfgtool. I don't know why you couldn't find the board, do you have another board to test?
