Hi,

 

I’ve been looking around and fiddling but haven’t been able to fix this issue. I’m trying to get PWM working, I have some code that worked before on an Overo-Air but with my new one it doesn’t work.

 

Calling:

devmem2 0x48088024 w 0x00000000

Gives me a Bus error

 

I have google quite a few things and have tried the following:

•             CONFIG_OMAP_RESET_CLOCKS – Disabling this in the kernel config (via menuconfig)

•             ARCH_HAS_HOLES_MEMORYMODEL – This is enabled in the config

 

Just to make sure I'm actually compiling the kernel right (with new config)

 

Bitbake –c menuconfig virtual/kernel

cp ${OVEROTOP}/tmp/work/overo-angstrom-linux-gnueabi/linux-omap3-3.2-r103git/.config \

   ${OVEROTOP}/org.openembedded.dev/recipes/linux/linux-omap3/Overo/defconfig

Bitbake –c clean virtual/kernel

Bitbake virtual/kernel

Bitbake omap-console-image

 

Then I flash the nand with the compile images in:

${OVEROTOP}/tmp/work/deploy/glibc/image/Overo/

 

If anyone has any suggestions as it if I'm doing the build/config wrong or what I need to fix in my config I would really appreciate it.

 

Thanks
