Android does not come up after increasing memory for ducati in kernel

Hello All,

I am working on a custom board based on OMAP4460. The Android release used is 4AI-1.4.

We want to increase the memory allocated for ducati by 10MB.

In the kernel we made the following change, in the file arch/arm/mach-omap2/omap4_ion.h

#define PHYS_ADDR_DUCATI_SIZE (SZ_1M * 105) to (SZ_1M * 115).

But after making the change we are observing the following crash

Is there any other change required in the kernel to increase memory allocated for ducati ?

Thank you for your time.

Any pointers will be helpful.

Thanks and Regards,

You will need to modify syslink driver - both A9 side and Ducati side.

Hi Mayank Mangla,

Thank you very much for the reply.

Can you please tell me whether the syslink driver is part of kernel or ducati ?

Thank you very much for your time.

Regards,

Sanjay

There is syslink driver on Ducati side and a RMSG driver on A9 side in the kernel. Hope this helps.

Hi Sanjay,

Syslink driver is described in details here

Georgi,

That is the wrong link for the IPC framework (RPMsg) on 4AI. The correct one is http://www.omappedia.com/wiki/Category:RPMsg

Sanjay,

How do you envision to split this increased size? The size on the kernel-side is combined for both Core0 and Core1 of the Ducati, so depending on where you want the increased memory, you have to make changes on the BIOS-side. You can look up the patches between 1.20.09.27 & 1.20.10.28 or 1.20.06.16 & 1.20.07.17 for reference from the sysbios-rpmsg tree @ http://git.omapzoom.org/?p=repo/sysbios-rpmsg.git;a=shortlog;h=refs/heads/rpmsg-1.20. If increasing heap, you would also have to adjust the heap size on the Ducati MM image.

regards

Suman
