Hi All,
I have started to work with the MCIMX6DLAICPU2 board and I have successfully build an sdcard image using the information found in the imx-yocto-L4.14.98_2.0.0_ga i.MX Yocto project user's guide.
I have successfully loaded the sdcard image on a Sony 16GB SDHC card, class 10, and the board and software boot correctly.
Before getting to this stage, I was using a Samsung 32GB EVO Plus micro SDHC card, also class 10, with an SDCard convertor. When using the Samsung card, the board would not boot.
I have tried all 4 SD speed selection options using the S1-9 and S1-10, but none of these work.
Since I can program the Samsung card and read out the information on my development PC, I know that the card has been programmed and does work.
Is there any information available or does anybody know why the Samsung card does not work with the Sabre board?
In addition, are there restrictions on what kind of SDcards can be used with the Sabre board.
Thanks in advance,
Olaf Heemskerk

Thanks,
this was information I hadn't seen yet.
Unfortunately I still can't find why the Samsung sd card does not work.
