LM3S3634 and LM3S3748 Platform Files

Other Parts Discussed in Thread: LM3S3634, SYSBIOS, LM3S3748

I'm trying to get our Stellaris project up and running with SYSBIOS on a dev board and for our design processor.  We are using the EKS-LM3S3748 development board for now, but our eventual target processor is the LM3S3634.  We're using CCS4.2.  I need to get an RTSC platform file for these two processors.  Is one available?

Also, when I try to create a new platform file from these, the first step is to choose the device family and device name.  CortexM3 is available for selection as device family, but neither of my devices is then available in the drop down for device name.  Is there a device file needed for these and is it available?  If not available, which one would be a good starting point for creating a new one, and where do I find these files?

 

Thanks.

  • I followed with the instructions mentioned on the Wiki on the following post and got to work with LM3S8965 with CCSv4.1.0:

     http://e2e.ti.com/support/microcontrollers/stellaris_arm_cortex-m3_microcontroller/f/471/p/75020/273432.aspx#273432

    Just have not tried with LM3S3748 or CCS4.2 but would hope the effort is similar.

     

  • I had seen this WIKI page.  It instructs you to choose ti.platforms.simCM3 as the platform.  Will this result in a build that will run on the LM3S3748 processor or the LM3S3634 processor, or just a build that runs in the simulator?  The WIKI page also has the following bullet point:

    • Currently only the Cortex M3 simulator is available as a development target. Support for hardware development boards will be added as its emulation device drivers become available.

    This is what led me to think that I need a different platform file for it to build for my specific processors.  Since there was no platform file for the LM3S3748 dev board I thought I would try to create one, but in doing so neither of my devices is availble as a choice for device name in the platform creation wizard.

    Check this link which has a wink demo to show how to make a new platform.

    We do not currently have explicit support in our catalog database for the LMS parts you mention above.  But from BIOS standpoint, these devices should be close the the LM3S5791except for the memory map.  BIOS only cares about timers and memory map and timers are same on this device.  So, if you start with memory map for the 5791 and then customize to match the your device's memory, you should be able to build and run the BIOS examples on your dev board.
