TMS320F28335: flash kernel sci bootloader

There are many threads regarding serial flash programmer on E2E. Please view those and this application report: www.ti.com/.../sprabv4b.pdf

Please read the application report and make sure also that your SCI communication is functioning properly.

You need to make sure you boot the SCI boot loader and also use the correct SCI GPIO pins. Perhaps try the echoback example first to test your connection.

Thanks for reply Sal but I reviewed this document but my problem go on.

Firstly I tried echoback test and it is correct.But I still get same error.

Please add the -v option to the command line to see a better output.

I will check this out shortly.

Sal thanks for reply,

-v option was already added.

I try with attached serial programmer exe. I get below message. I   will try another computer or  How I execute with Visual Studio?

This app can't run on your PC.

To find a version for your PC. check with the software publisher.

Thanks

I have gotten this working with the control card and with a Windows 10 machine. I built it with windows 10 as well.

sal

Thanks for reply Sal,

I succesful with your attached files but my project is not work. My project is linked and mapped flash and build option is "${CG_TOOL_HEX}" "${BuildArtifactFileName}" -boot -sci8 -a -o "${BuildArtifactFileBaseName}.txt"

What can I do another something?

Thanks....

Regards

Can you first try building the LED blinking example like I have and see if you can load that flash application?

We need to take small steps to see what may be wrong. Start with a small application and then build up.

Also, you can load you flash application via CCS and then dump the contents to the file. Then load your application with the serial flash programmer and dump the contents. Then you can do a diff.

Sal thanks for helping .My project works but I want to know one more thing. My bootloading time is 2-3 minutes.Is it normal? Can I make shorter time ?
Thanks

Regards...

My f28335_nonBIAS_flash.cmd file is not include  that

ramfuncs : LOAD = FLASH_ABCDEFGH, PAGE = 0
RUN = L0123SARAM, PAGE = 0
LOAD_START(_RamFuncs_loadstart),
LOAD_SIZE(_RamFuncs_loadsize),
RUN_START(_RamFuncs_runstart)*/

so I added.It works.

2-)When I change baud rate and -v , to much things not change but thanks for advice.

3-) When power on in scıa boot mode , program is not loaded.

Am I always  load program start? I want to work last program (before power off).Is it possible?

Please rephrase your question. I am not sure what you are asking?

sal

In scia boot mode(GPIO 84=0) when I power on,
There is not program. I bootloading for program. I want to loading program permanently in scia boot mode.

What are you means two boot mode select pins
And also after bootloading, restart and worked but i powered off and then power on but there is program

Thanks

I saw this table. I am configured sci boot mode(GPIO87,86,85=1 84=0) . I guess, I couldn't tell my problem completely.

I make sci bootloading.There is no problem.The  program loads, restarts and works. There is no problem also.

but I power off, then power on (hardware) . There is no program  in sci boot mode. When I jump to flash (GPIO84=1(hardware) ), program there

So  I make bootloding again or jump to flash(GPIO84=1(hardware)) for access program  but I look for way that permanent program in sci boot mode.

Thanks for reply

I want to sci boot (GPIOs 87 86 85 84 1 1 1 0)

I give  example with blink led. I make sci boot and leds blink. There is no problem

But when mcu power off then power on leds don't blink .(still gpios 87 86 85 84  1 1 1 0)

Thanks

Regards.

So I load aplication at begining every time in sci boot mode.Is it right?

Yes I know.My question is relevant leds blink after mcu power resets. Is it possible?

I have a question.
What does your boot ROM mean exactly?
  For example, "InitBoot.asm"?
