[beagleboard] DS3234 clock on SPI1

Running kernel 4.4 and trying to read a DS3234 clock on the second SPI port I can suppress the HDMI pins in uEnv.txt with: dtb=am335x-boneblack-emmc-overlay.dtb optargs=cape_disable=bone_capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN (uEnv.txt isn't loading the "universal overlay".)

[beagleboard] Kernel 4.4 and SPI

I've been trying to port the driver for a SPI rtc, the DS3234, from the 3.8 kernel to a recent 4.4. After minor changes the cape manager loads the dts file sucessfully, and the slot entry and /dev/rtc1 appear, but reading and writing to the clock fails. Checking the pins and pin groups it

I've been trying to build a BBB kernel using Robert Nelson's scripts from the instructions on eewiki; however, there seems to be no way to download the git sources. Does anyone have a working script for this? I'm building on a 32-bit machine, and the Linaro compiler is 64-bit, but if I can

Okay, I'm officially confused. I've been trying to increase the speed of my BBB from the default 550MHz to 1GHz, and failing; this is with the elderly 3.8.13-37 sources. After a few failures I went back to a seriously ancient kernel, just to get something to run, and found that the

[beagleboard] Setting the CPU speed.

I've been looking at the speed of my BBB and not really understanding what's going on. The files under /sys/devices/system/cpu/cpu0/cpufreq show that the performance governor is in use, but the speed is a constant 550,000 whatever the load. The scaling_setspeed unsupported entry probably
