No response from ConnectCore6 SBC after tftp uboot update

0 votes
I followed the docs and used yocto to build a system for a ConnectCore6 SBC.

Again, following the docs, I used tftp to update the u-boot. The update seems to have gone OK, but afterwards I get no response from the board.

Did I brick the board? Is there a way to get it back?

Here is the log of the update:

You are using ConnectCore 6 SOM variant 0x13, which assembles a i.MX6 duallite, and 512 MB of RAM.

The correct U-Boot image is named something like:
u-boot-ccimx6dlsbc512.imx

Note the 'dl' for duallite, and '512' for 512MB ram. Use that U-Boot image and it will boot.

(And it is a CC6, not a CC6UL)

Thanks.

Unfortunately, I no longer have that SBC, I have the ones I was supposed to get in the first place, which somewhat explains my confusion.
