Firmware Upgraded

Hi Masky,

I've never heard about a firmware upgrade software for TMS controllers and I guess there isn't any! \\

Hello Gautam,

so I understand the only way to upgrade the firmware is?...CCS and an emulator? 

Hi Masky,

As per the device data sheet (sprs230n.pdf) : http://www.ti.com/litv/pdf/sprs230n  page35:

The Boot ROM is factory-programmed with boot-loading software. Boot-mode signals are provided to tell
the bootloader software what boot mode to use on power up. The user can select to boot normally or to
download new software from an external connection or to select boot software that is programmed in the
internal Flash/ROM.

You have several options to boot from: flash, SCI, I2C, eCAN, parallel I/O. 

You can upgrade your firmware for instance with this tool over SCI: http://www.elprotronic.com/flashpro2000.html

I hope this helps,

With best regards

Tomas

Hello Tomas,

but I have my own hardware and I don't need an adapter, and I guess with Elpotronic SW is mandatory to use the Elpotronic adapter. In any case, I'll check the SW.

Hello Masky!

Do you need to upgrade via USB necessarily? There is some solution via RS232.

Igor 

Thanks Thomas for the info !

Hello Igor,

yes, I need to upgrade via USB, because my hardware is the same for differentes controllers.

Ok, thank you Tomas.

Hello Tomas,

following with this issue, I need to generate a .hex file from the .out file. Using the hex2000.exe utility, I convert the out file into 2 files: .a01 and .a00, but I really need an hex file. 

To get this file I've written hex2000.exe -a filename.out in the Windows MS-DOS prompt. There is something wrong?

Hi Masky,

As stated in the C2k assembly language user's guid,e page 260. http://www.ti.com/lit/ug/spru513e/spru513e.pdf hex2000 utility has a couple of options.

You may want to try this: hex2000.exe -romwidth=16 -memwidth=16 -i masky.out -o masky.hex

On the other side you can also set your path to hex2000.exe in Elprotronic programmer and it will automatically call the conversion utility with the proper parameters for you.

FlashPro2000->Setup->Preferences

I hope this helps,

With best regards

Thank you Tomas, I can generate the hex file in the windows prompt, but... Could I do this into CCS? I checked through Menu --> project --> Buiil Option --> General tab --> Final build steps --> and written hex2000.exe -romwidth=16 -memwidth=16 -i operador.out -o masky.hex 

But I get the follow error:

>> WARNING: invalid option: -romwidth=16
>> WARNING: invalid option: -memwidth=16
>> FATAL ERROR: cannot open input file 'operador.out': No such file or directory
(aborting)

Hello!

Try thus:

hex2000 operador.out -i --romwidth=16 -o masky.hex

Regards,

Igor
