BIOS-USB Example Programs (6747-Processor) Using OMAP-L137 EVM

Hello Dan,

Please mention the versions of the all tools you used. I will check & let you know.

Also, from the file names, i am assuming that you are using BIOUSB device mode for OMAPL137. Please confirm the same.

Regards

Prasad

The versions that I am using are:

CCS                              3.3.82.13

DSP/BIOS                    5.41.10.36

Code Gen Tools            6.1.19

EVM OMAP-L137      Rev-H

EDMA 3 LLD              1.11.02.05

ERTFS                         1.10.02.32

PSP Drivers                 1.30.00.05

BIOSUSB                    1.10.03

I am not exactly sure about your second question. I am developing on the Spectrum Digital OMAP-L137 DVM, and I am trying to compile the sample project :

C:\Program Files\Texas Instruments\biosusb_01_10_03\packages\ti\biosusb\examples\usbdevmsc\build\C6747\ccs3\usb_dev_msc_sample.pjt

In CCS-setup I tried an OMAP-L137 setup and a C6747 setup. Does this help?

If I go to the ProjectàBuildOptionsàLinker…

Is there something missing here?

Hello Dan,

In your first post you have written, "I am working with the OMAP-L137 EVM board and I am trying to compile the BIOS-USB example programs to learn about FAT32 file access to a USB-Thumb-Drive using the 6747-Processor."

From this statement, i think you should use BIOSUSB in HOST mode.

Explaining it further:

If you want to access any USB-Thumb-Drive connected through OMAP-L137, you should use BIOSUSB in host mode. Here OMAP-L137 is a host, which is detecting/readinh/writing USB-Thumb-Drive.

And if you want to, use OMAP-L137 as mass storage device, which will be detected on your computer as USB device, after connecting to it, then you should use BIOSUSB in device mode because now OMAP-L137 is working as device. 

Please clarify this you want device mode or host mode.

Also, I am not seeing any environment variable for RTFS, please declare that.

Regards

Prasad

Sorry, I had RTFS defined but missed putting it in my email.

 RTFS_INSTALL_DIR                        c:\CCStudio_v3.3\rtfs_1_10_02_32

Yes, I want to use BIOSUSB in host mode. More specifically, I want use the USB-port to make my design field upgradable. When a USB-stick is plugged into the EVM board, I want my program to search for a particular file name (like) “NewBootUpgrade.bin” and if it exists, I want my program to burn this file into the SPI-Flash chip. I need the FAT-32 file system because I would like to be able to email a customer a new boot-image and have him copy it to a USB-stick (from his PC), then carry it over to my product and plug it in to perform a software upgrade.

The first step that I want to take is to compile and run an example program that can read and write to a USB-stick. 

I am now compiling :

C:\Program Files\Texas Instruments\biosusb_01_10_03\packages\ti\biosusb\examples\usbhosthid\build\C6747\ccs3\usb_host_hid_sample.pjt

I get the same link error.

Dan, 

I am unable to see the contents of the image. you can mail it to me on my mail id (pvjoshi@ti.com).

I am copying the <usb_host_hid_sample.pjt> file here. please compare it with your file.

Also, please make sure that, you add the correct <ProjectDir> path in .pjt file.

Dan,

In the image, there are two errors. What is the other error you are getting other than "_commonInit" symbol not found?

Regards

Prasad

I emailed you a new image showing the entire output.

I compared every line of my project and yours. They are identical (eccept the recent change that I made to "ProjectDir" setting).

Not sure if this will help. I don't have my EVM in front of me but I googled about for a map file. Seems "_commonInit" lives here:

ti.pspiom.platforms.evmOMAPL137.evmInit.a674 : common_evmInit.obj (.text:_commonInit)

Maybe it got removed or renamed in your version of the PSP lib. Version 01.30.01 worked my installation for the USB dev examples. Never tried the USB host examples.

That might be getting closer to my problem.

I have the evmInit.a674 files. However I do not understand exactly what they are. CCS interprets any file extension starting with and ‘a’ as an assembler file. However; these are archive files. I am not familiar with these. I have compiled and linked to library files before. What are these archive files and why can’t the example USB program link to it? If I try to add it to the library folder in CCS it adds it to the Source folder because it thinks it is an assembler file. I have recompile this archive but that does not help. Should I try to recompile this as a library?

I am guessing CCS archives are like Liinux library archives, a container for compiler object code. I don't remember having to compiler those. I think they came as pre-compiled binaries only.

I took a look at the User Guides for BIOSPSP 01.30.00.06 and BIOSPSP 01.30.01. The newer version contains a new section noting commonInit(). Implies that something got added between 01.30.00.06 and 01.30.01 . Maybe try upgrading your PSP.

Hello Dan,

PSP Driver version 1.30.00.05 is released for supporting DSP/BIOS 5.33.06.

While, PSP Driver version 1.30.00.06 is released for supporting DSP/BIOS 5.41.00.06

PSP driver version 1.30.00.05 do not have common_evmInit.c. Therefore, the lib (ti.pspiom.platforms.evm6747.evmInit.a674) created by building the project <evmInit.pjt> in the folder pspdrivers_01_30_00_05\packages\ti\pspiom\platforms\evm6747\build\ccs3 does not have commonInit symbol, which is required while linking it to the USB project on DSP/BIOS 5.41.10.36 & onwards.

Therefore, I suggest you, upgrading your PSP Driver version & moving to the PSP Driver version 1.30.00.06.

This will solve your problem.

Regards

Prasad V. Joshi

If my reply answers your question please mark the thread as answered.

I am having trouble finding this upgrade. The PSP link :

http://software-dl.ti.com/dsps/dsps_registered_sw/sdo_sb/targetcontent/psp/bios_usb/index.html

only has one version. Where do i download version 1.30.00.06?

That's a old USB package with a link to an old PSP version. The PSP packages are publicly available here:
