Part Number: PROCESSOR-SDK-AM437X
Other Parts Discussed in Thread: SYSBIOS

Tool/software: Code Composer Studio

I can´t find in version 7.2.0.00013 of CSS how to change the value of EXT_RAM.

I would like to change it from 0x8000000 (128MB) to 0x40000000 (1GB).

I beleive the "linker.cmd" file is generated by CCS at build time. This file has the following statment: EXT_RAM : org = 0x80000000, len = 0x8000000.

Are you using the RTOS Processor SDK? If so, the linker.cmd is generated during build. To make changes to the memory configuration you would need to modify the RTSC platform. I will request the SYS/BIOS experts to provide more information on that.

Yes, I am using the RTOS Processor SDK: ti-processor-sdk-rtos-am437x-evm-04.00.00.04
Thanks,

Hi,

The platform is defined by the SYSBIOS, it is irrelevant to CCS version. In your CCS ------>Project----->RTSC Tools---->Platform ----->edit/view, select your platform: and edit there. Or you can create a new platform.

Hi Eric,

The form presented after I select CCS ------>Project----->RTSC Tools---->Platform ----->edit/view, is pointing to "c:\Users\mborges\myRepository\packages\", which is empty. It does not show package or core to select.

I´ve tried "c:\ti\bios_6_46_05_55\packages\ti\platforms\evmAM437X\" and "c:\ti\bios_6_46_05_55\packages\ti\platforms\evmAM437X\package\", but nothing changed, no package or core to select.

Regards,
Marcio

Hi,

Please see my picture posted earlier, it is c:\ti\bios_6_46_05_55\packages directory to open, don't go below to ti\platforms\....

My fault. "c:\ti\bios_6_46_05_55\packages" works.
Thank you.
