TMS320F28075: TMS320F28075

Hi Yin Seng,

Looks like your installation is missing the driver somehow.  Did you check for updates in CCS and install any latest updates?  Hope you are using the latest CCS 10.x version.

Do you see below folder in your CCS installation directory? 

ccsxxxx\ccs\ccs_base\common\uscif\xds110

In your Uniflash installation directory, do you have below folder?

uniflash_6.2.0\deskdb\content\TICloudAgent\win\ccs_base\common\uscif\xds110

Thanks and regards,
Vamsi

Both also available, I am using latest is uniflash 6.0.0, and CCS6

yes Available - ccsv6\ccs_base\common\uscif\xds110

yes available - uniflash_6.0.0\deskdb\content\TICloudAgent\win\ccs_base\common\uscif\xds110

besides, i will download and install CCS10 and see

Hi Yin Seng,

Ok, let me know how it goes with CCSv10.

I would suggest you to take a look at: https://e2e.ti.com/support/microcontrollers/c2000/f/c2000-microcontrollers-forum/729543/faq-product-change-notice-pcn-20180523001-1-and-pcn-20200115000-2-for-tms320f2837x-and-tms320f2807x-devices 

Minimum CCS version recommended is CCSv9.x.  Anyways, you are going to try CCSv10.x.

I will check with our CCS team meanwhile on why it is not showing up for you.

Thanks and regards,
Vamsi

Hi, With CCS10, selection is there, when i click the verify, i getting failed on scan JTAG chain.

Execute the command:

The target's JTAG scan-path appears to be broken
with a stuck-at-ones or stuck-at-zero fault.

I am using External JTAG tool, able to scan and detect the JTAG device.

Hi Yin Seng,

You said you are able to program via FlashPro.  Did you already program something in flash then?  Also, did you use the JTAG option or the SCI option of the FlashPro?

How are the boot mode pins configured?  Hope you are trying it in wait boot.

Thanks and regards,
Vamsi 

Hi Vamsi,

I am using JTAG-FAST interface for programming, not SCI-Boot, is this the question you ask?

I just check through the connection, GPIO84 and GPIO72 is setting high now, so should be Get Mode, do i need change to wait boot mode?

But base on datasheet, EMU boot mode for GPIO84/72 is don't care, so any related to current programming portion?

Hi Yin Seng,

Thank you for the clarification.

Please try wait boot mode with boot GPIO pins and let me know if that works.  It helps emulator to make stable connection with the device.

Thanks and regards,

Vamsi

Hi Vamsi,

Been try for tied GPIO84 to GND, result getting same failure for both Uniflash and CCS(test Connection)

Hi Yin Seng,

This is not a flash programmer (Uniflash or CCS plugin) issue.  Connection to the device is not successful (hence flash programmer did not even start running).  

This seems like your board or emulator HW issue.

Try to isolate the issue by changing the device, the emulator, the board (maybe you can try TI control card) and see how it goes.

Here is a thread with similar error that may help: e2e.ti.com/.../faq-ccs-launchxl-f280049c-advisement-emupack-8-0-903-4-incompatible-with-launchxl-f280049c

Hi Vamsi,

we just try XDS510 same setup, program without any problem, but XDS510 already obsolete so we bought XDS110.

Today been try for two unit XDS110 getting same error, please confirm is it XDS110 not able to perform the program, or need any additional setting/setup?

Besides i am getting serial number 0

is it possible serial number all 0's?

Hi Yin Seng,

XDS110 can be used with F28075.  We used it extensively.

Take a look at this post: https://e2e.ti.com/support/microcontrollers/c2000/f/c2000-microcontrollers-forum/925801/ccs-tms320f28075-xds110-programming-error-sc_err_path_broken 

Thanks and regards,

My board design connector as below, the design is for debugger use, i am using the provided adaptor from 20pin TI 14 pins, so all connection no problem.

and the TRST pull down resistor product designer to be correct one. 

instead, as i mention XDS510, plug n play without any issue.

Hi Yin Seng,

I will ask our JTAG expert to take a look at this.  Please expect a reply early next week.

Thanks and regards,
Vamsi
