TowerTech TT3201 CAN cape locking up beaglebone

I pulled out my beaglebone to mess with it yesterday and updated to the newest Angstrom image. I’ve tried the full image and the small image and they both lock up during boot. If I go back to an older image 4.09.12 the image boots just fine. If I take off the TT3201 cape the new images boot just fine. Thus I’m thinking it’s something in the new images that are causing the issue. Can anyone confirm this? Would be nice to know if it’s a hardware issue or software issue.

Thanks,
Travis

I've run into the same issue yesterday and after spending a few hours on it I'm pretty sure it's being caused by SPI being initialized *before* mmc. In older kernels it was the other way around but with the eMMC and SDIO wifi cape we changed that around to support both mmc0 and mmc1. I have some other issues to address today, but I hope to have a solution before the weekend.

Hello,

by the way TT3201 isn’t support by Angstrom images 2013-06-06. I’ve received a new kernel from Towertech support which was working fine with my BeagleBone Black and the TT3201 cape.

Hello,

Is there any step by step guide to update the kernel from Towertech?
