Cannot Boot from SD debian 9.x on BBB rev c with 2G emmc

[Claude Arpin]

Hello,

I have a number of BBB rev C with the 2G emmc and I have tried to boot Debian 9.x from the micro SD without success. I finally tried both Debian 8.x and 7.x and they works fine.  I noticed that Debian 9.x uses ext4 as the  format and I beleive the older releases use  ext3. Could this be the reason my BBB do not see the SD and does not boot from it with debian 9.x?

Thanks

No, plug in a usb serial adapter into j1 and let's find out why..

I didn't know there were 2GB rev C releases... Every document I've
encountered states that rev C was 4GB

What version OS is /in/ the eMMC?

Hello Dennis, the OS is Debian 7.5, here is apicture of the side sticker.

With the j1 serial port I could see my problem was the boot process u-boot.

All the best

That's pretty archaic -- the last 7.x release (at least, in my archive)
was 7.11, and that was almost 2.5 years ago. 7.5 is four years old.

The odds are very good that the u-boot that is running is designed for
kernel-time device tree loading, but since the mid-8.x Debian, the kernels
expect u-boot to load the device tree.

The image doesn't provide any information for me -- both of my BBB
units have a sticker with 0615BBBK0412 under a bar-code. At best, it
identifies a manufacturer internal stock number.
