Load a dto at startup - Githubissues

TigerClaw33 commented 8 years ago

Hi, I try to load the dto for the I2C-1-Bus and a second dto for my extern ADC. cape_enable=bone_capemgr.enable_partno=BB-I2C1 works.

cape_enable=bone_capemgr.enable_partno=BB-I2C1 , BB-ADC-GPIO

didn't work. Only BB.I2C1 is loaded:

root@beaglebone:/# cat /sys/devices/platform/bone_capemgr/slots
 0: PF----  -1
 1: PF----  -1
 2: PF----  -1
 3: PF----  -1
 4: P-O-L-   0 Override Board Name,00A0,Override Manuf,BB-I2C1

And I don't want to execute the following command after every startup:

root@beaglebone:/# sudo sh -c "echo 'BB-ADC-GPIO' > /sys/devices/platform/bone_capemgr/slots"
root@beaglebone:/# cat /sys/devices/platform/bone_capemgr/slots                  0: PF----  -1
 1: PF----  -1
 2: PF----  -1
 3: PF----  -1
 4: P-O-L-   0 Override Board Name,00A0,Override Manuf,BB-I2C1
 6: P-O-L-   1 Override Board Name,00A0,Override Manuf,BB-ADC-GPIO

Why the command in the /boot/uEnv.txt is only working for BB-I2C1 but not for the second dto?

Thanks.

Well, drop the spaces...

cape_enable=bone_capemgr.enable_partno=BB-I2C1,BB-ADC-GPIO

This was a copy and space mistake. They are drop

Make sure the initrd.img has your addon "BB-ADC_GPIO" *.dtbo:

sudo update-initramfs -uk `uname -r`

Thanks, I tried this a few weeks ago but maybe forgot to set "-t" to override.

sudo update-initramfs -ukuname -r-t

works!
