C6748 Development Kit

Moving this thread to the C67x forum.

Hi Dmitriy,

Please check that you are getting "BOOTME" message after you did following boot settings on LCDK board.

UART boot: (BOOTME message)
set switch 2,4 ON and 1,3,5,6,7,8 OFF

NAND boot:
set switch 2,3,4 ON and 1,5,6,7,8 OFF

By default, we ship LCDK with demo code flashed on NAND flash.

Hi Shankari,

We are seeing the "BOOTME" message when booting from UART2. However, there is no serial output when we try to boot from NAND, baud rate 115200.

So, we tried reflashing the demo code. We used AISgen.exe to create demo.ais from demo.out, in the C6748 StarterWare software package (C6748_StarterWare_1_20_04_01\binary\c674x\cgt_ccs\c6748\lcdkC6748\demo\Release\boot.out). We then set S1 to 01010000, and flashed this to the LCDK using the command:

"sfh_OMAP-L138.exe -flash_noubl -flashType NAND -targetType C6748_LCDK -p COM6 demo.ais"

The flashing operation completed successfully, and when we tried to boot from NAND again (setting S1 to 01110000) we still saw no output in the serial terminal program.

Is this the correct demo program that ships with the board? Is there some other program we should be flashing instead to see some output in our terminal program?

Thank you

Hi Dmitriy,

Thanks.

Is this the correct demo program that ships with the board? Is there some other program we should be flashing instead to see some output in our terminal program?

We ship LCDK board with the following flashed binary which has both finger print sensor demo binary and facedetect binary.

C:\ti\c6sdk_02_00_00_00\demos\flash\lcdk\IT_IS_ALL_ABOUT_YOU.bin

FYI: In newer LCDK board, you can't see the finger print sensor due to obsolete sensor.

Did you install the C6SDK ?

Refer to the following TI wiki pages.

Here I flashed that binary and able to get the expected output.

Good morning!

>> We ship LCDK board with the following flashed binary which has both finger print sensor demo binary and facedetect binary.

From the beginning we didn't receive any output from the board. That's why we try to reflash demo program.

>> Did you install the C6SDK ?

Yes, we did.

>> Here I flashed that binary and able to get the expected output.

Following for your steps

dip: 01010000

dip: 01110000

So, as You can see - no output.

Any suggestions?

Thank You in advance.

Dmitriy.

Hi Shankari

Finally it starts flashing and I can't give you any good explanation of it.

BTW

After we were able to test and establish a toolchain including these :
- ti-cgt-c6000_8.0.3
- C6748_StarterWare_1_20_04_01-Linux-x86-Install
- DSPLIB 3_4_0_0
- MATHLIB C674X
(Ps : we're not using CCS, we're relying on the old fashionned makefiles and sources)
we tried a program that requires 36 seconds to run on a general Purpose CPU [beaglebone' Arm A8]
but it took 3 minutes for us, and then 2mn30 after using compiler's optimization flags and the steps mentionned in the developer's guide.

We would like to know more details about the optimization. we know that the C6748 is at least 10 times faster than the Arm A8 (BBB) in term of megaflops so we're probably missing something.

Best regards.

Dmitriy
