Other Parts Discussed in Thread: OMAPL138

Hello Everyone,

                               Am new to TI family. Currently , am working on OMAPL137. As per the previous conversation had on the TI forum I came to know that starter ware for OMAPL137 is not available . Also, we are building our custom board for OMAPL137. IT will take more time to reach us. So, i have planned to buy OMAPL138 development board and make use Starter ware code to check on the development board. Since the starter ware is already available . Major difference what i observed was that OMAPL137 falls under high temperature category and OMAPL138 falls under normal temperature.So, below are my queries.

1.Can i port the OMAPL138 starter ware example code to my custom board which consists of OMAPL137 by making minimal changes??

2. Is there any major difference between OMAPL138 coding and OMAPL137??

3. What are the key things i need to take care while coding for OMAPL137??

4. What is percentage of efforts i need to put  for porting ??

Waiting for your reply at the earliest!!

Thanks & Regards

    Hi Naveen,

    You can concentrate some simple GPIO example code.
    Just try to port GPIO example code with its dependency library.
    Try to build it for OMAPL138 and understand what are all the libraries used etc.,

    Hi,

    Thanks for your post.

    For your Q#1, yes, it is possible to port the omapl138 starterware example code to omapl137 based custom board.

    To address Q#2 & Q#3, the major challenges in coding perspective would be while porting it to OMAPL137, it would require h/w platform level code changes, platform level code changes (syscfg, soc, psc, pinmux setup, interrupts etc.)

    To address Q#4, In my opinion, (30-40)% of coding efforts would be required for porting L138 starterware based code to L137.

    Thanks & regards,
