TMS320F28234: both debug and release mode fails

Part Number: TMS320F28234
Other Parts Discussed in Thread: C2000WARE, , TEST2

I was trying to add IQ math library to existing project for pwm generation which was working fine. But then following error comes up during both debug and release mode. Tried closing and restarting debugger and ccs but didnt solve the issue. Also removed the IQ math settings and used original ram and flash linker files in c2000ware.But same error comes up.

on Release mode:

C28xx: GEL Output:
ADC Calibration not complete, device is secureC28xx: Flash Programmer: Warning: The configured device (TMS320F28234), does not match the detected device (). Flash Programming operations could be affected. Please consider modifying your target configuration file.
C28xx: GEL Output:
ADC Calibration not complete, device is secureC28xx: Flash Programmer: Device is locked or not connected. Operation cancelled.
C28xx: File Loader: Memory write failed: Unknown error
C28xx: GEL: File: C:\Users\PEG145D\Desktop\ldvc\boat\code\test2\Release\buckpwm_c.out: Load failed.

on debug mode:

C28xx: GEL Output:

Hi,

Your device might have got locked .

Pls refer a similar post of this topic

i went through all the links provided. When i try to use debug mode with a new target configuration file following message occurs

"Break at address "0x3ff9ce" with no debug information available, or outside of program code"

Yes i could see 000 on 0x33FFF8 which implies a locked device right.

But i dont particularly remember a power supply failure during flash programming. But i had to abruptly close the ccs ide once during the flash programming . like to know whether this could corrupt the csm locations.

Hi,

Instead of trying to load the .out, can you try to launch the debug session and only try to connect to the CPU and then read from the memory browser.

This help in determining whether the device is locked or not.

Hi,

Thanks for the reply.

I could saw that password locations as 0x000.So now i tried with new controller.

but now it is showing this error. I remember in the previous case the problem started with this error first

What may be reason?

Hi,

I find that "0x3ff9ce" corresponds to symbol initboot. Is it the problem with gpio boot setting?.But from c2000 workshop series what i understand is that with emulator connected boot mode is determined by emulator key.

Nandu,

Yes, 0x3FF9CE corresponds to InitBoot. After this, it should execute the TI Boot Code and then depending on the boot select pins (GPIO) it should boot

You can load the boot symbols and then debug . The boot code is available a <C2000Ware>\libraries\boot_rom\f2823x

HI,

I have gpio settings for boot to flash.

Do i have to manually add boot rom files in c2000ware to project for debugging? How to load the boot symbols?

Regards,

Nandu

I tried to execute a new example code from c2000ware. Initially it showed same problem

"Break at address "0x3ff9ce" with no debug information available, or outside of program code"

But now it is showing following error.

"Severe error during register,execution.It aooears that the target is being held in reset.This may be due to WIR...."

What may be the reason

Nandu,

Similar to load program , there is a option to load only the symbols by pointing to the boot rom binary file <C2000Ware>\libraries\boot_rom\f2823x\xxx\rom_sources\Debug

You can load it and try to debug.

Best Regards
