SYSBIOS with OMAPL137 - Device Driver Development

Hi Pinakin,

I am guessing you are looking for drivers for the C6747 DSP in OMAPL137. I would suggest getting the C6748 (OMAPL138) SDK (www.ti.com/.../biossw-c6748) and reworking the drivers you are interested in to make them work with OMAPL137. Since OMAPL137 and OMAPL138 are similar, it should be a fairly simple job. Typically the differences might be that the interrupt number for a particular peripheral may be different or the base addresses are different. The rest of the driver should remain the same.

Best,

Hi Ashish, 

I am actually looking for uart, spi and i2c drivers for omapl137-ht. Also I was planning on implementing a driver to talk to external adc via SPI. This is why I was wondering if there is a driver development document. 

Hi Ashish,

Your information is very helpful. I downloaded the software for TMS320C6748 SYS/BIOS Software Development Kit (SDK). I then created a new project in CCS for IO_Stream example for OMAPL137 (not for DSP core but just for ARM 9 - single core). At the moment I just want to test the UART functionality of OMAPL137. I then selected all the RTSC options available. When I build this project it fails with the following 2 errors:

1. fatal error #1965: cannot open source file "C:/...../Debug/configPkg/package/cfg/stream_pe9.h"

2. can't find the library 'lib/ti.targets.arm.rtsarm.ae9' specified by pakage ti.targets.arm.rtsarm. It was'nt found along the path '.....'.

Is there something that I am missing here. I just want to build an example to understand the working of UART and SPI drivers.
