Failed to start Cape Manager Service.

[kevin...@wintec-inc.com]

During boot I am getting a "Failed to start Cape Manager Service." failure

I have a custom cape that gets loaded via /uEnv.txt along with BB_SPIDEV0, both show up in slots

my problem is that the disable for HDMI does not work as the pinmux still shows the hdmi pins as assigned.

I still get: [FAILED] Failed to start Cape Manager Service.

I did edit /uEnv.txt and /biit/uenv.txt while mounted:

mount /dev/mmcblk0p1 /mnt/card

did not look to matter.

? should it be bone_campmgr.partno or capemgr.enable_partno

I have seen/tried both

BB-SPIDEV0 uses P9.17, dtb=am335x-boneblack-emmc-overlay.dtb doesn't
touch P9.17, thus "YOUR" BB-GPIO-1553 is taking P9.17..

You need to fix that..

[kevin...@wintec-inc.com]

Out BB-GPIO-1553 does not use P9.17.  If I remove the enable for SPIDEV0 from uEnv.txt, the capemgr error goes away, SPIDEV0 looks to load but does not work.

Did you actually try /dev/spidev*?

ps, you really should upgrade from: 4.1.38-bone-rt-r24 -> 4.4.x-bone-rt-ry

As there was a lot of fixes in 4.4.x

[kevin...@wintec-inc.com]

Yes, I am developing a 1553 Cape that uses SPI.  Have a Demo that works.

The demo says it initialized spi but no data is transferred.

I will up grade the kernel, 

I will retry it to verify SPI

I am booting from the SD card, my uEnv.txt are on it.  does something in the eMMC get run first??

BTW I am a newbie to Linuc/Beaglebone not to embedded Realtime.

Thanks for the help.

[kevin...@wintec-inc.com]

Why 4.4x vs some of the newer ones like 4.9.5  If I have to rebuild why not go to newer?

Or is 4.4 stable?

I retried leaving out SPIDEV0 and I do not get SPI 0.

When I add SPIDEV0 I get the metioned error.

Also, I am building 4.4.47-bone-rt- is there a recommented u-boot version to use?

Hello Kevin,
I am using 4.1.33-bone-rt-r24 kernel for 1553 Drive,too . I should disable HDMI pin. Did you achive disabling HDMI pin ?

Hello kevin,

I am using 4.1.38-bone-rt-r24,too for 1553 Driver code and I should use this kernel for Driver. Did you achieve disablining HDMI?
