TMS320F28027 load programs in chip

Dear gautam,

Thanks for your help but few more questions

1. The same emulator can be used for 16 bit micro controllers, 32bit micro-controllers/ARM. Otherwise whether the above said debugger is IC specific.

2. Also can u suggest any DIP package microntroller of DIP package with  more than 20 GPIO and with 6 ADC ( 12bit).

3. As microchip is providing free MPLab software for software environement , Is Texas providing such kind of support , Whether that support is free of cost or chargeable.

4. After installation above link software XDS100 when I open it is not able to open. Again it is asking to install it. Also i am not able to get the PCB layout.

Regards

Ashutosh

1. The same emulator can be used for 16 bit micro controllers, 32bit micro-controllers/ARM. Otherwise whether the above said debugger is IC specific.

Support for the following processor cores: TMS320C28x, TMS320C54x, TMS320C55x, TMS320C64x+, TMS320C674x, TMS320C66x, ARM 9, ARM Cortex R4, ARM Cortex A8, ARM Cortex A9 and Cortex M3

Please go through this link for more details: http://processors.wiki.ti.com/index.php/XDS100

2. Also can u suggest any DIP package microntroller of DIP package with  more than 20 GPIO and with 6 ADC ( 12bit).

None of the C2000 series come in DIP package. You can use a converter though.

3. As microchip is providing free MPLab software for software environement , Is Texas providing such kind of support , Whether that support is free of cost or chargeable.

Yes, CCS is available for free for C2000 devices if XDS100 emulator is used.

4. After installation above link software XDS100 when I open it is not able to open. Again it is asking to install it. Also i am not able to get the PCB layout.

1. What do u mean by converter through.

2. DIP IC are easy for soldering hence we prefer most . Howe ever we need cost effective solution

3. Microchip also provides the interfacing module on which we have to mount the chip so that to upload the programm from MPLAB or Keil. after that u can put back into ur PCB. Does Texas provides this kind of interface.

4. The cost said TMS320F28027 is 3.2/1kU at texas site does it mean it is it is 3.12 dollar for 1000 pieces. As on the element14 website it is showing 544Rs /piece which sounds it is costly IC.

5.Also suggest any cost effective debugger/emulator for MSP430G2553 along with that please suggest the software for interfacing the chip .

Dear Sir,

I am using 28069 Piccolo control stick, As per my design requirement I need two control stick to execute two parallel program. I am using Code composer V4 for uploading the programs. However, since I have to upload programs in two separate control stick and make them run. I have thought to one control stick I will upload in flash memory, so that it can run independently, only it needs to be powered, However for other control stick I require grpahs and online control facility of code composer, hence it needs to be connected to PC and code composer permamaently.

Thus in view of above I request you to suggest how to upload program in flash memory through code composer, so that it cannot be earased if the power to the stick is OFF, Also it will start its operation once the power is up. Moreoevr, if I need to overwirte the programm in flash meomory will it be possible through code composer studio.

Please guide urgently

Dear Sir,

As I am short of time, can u indicate step by step procedures to follow.

Let me know what are changes that I have to make to my existing program to carry out the job.

Also suggest me by adding few files of above said example to my project file will it be sufficent.

Please indicate some easy and fast steps to follow.

If you're in a hurry, the above method 2 is the best option:

Import this project: "flash_f28069"

C:\ti\controlSUITE\device_support\f2806x\v136\F2806x_examples_ccsv5\flash_f28069

The linker file (.cmd) in this project is already designed for flash execution.

Just paste your code in that example.

Gautam

Dear Sir,

I have gone through that programm.

If I add these to main programm

   MemCopy(&RamfuncsLoadStart, &RamfuncsLoadEnd, &RamfuncsRunStart);

InitFlash();

and further add the file naming 28069.cmd and delete from project 28069_RAM_ink.cmd

will it be sufficent to upload the prorgamm in flash

Also,  After that what are the setting in code-composer to upload proramm in flash (not permamently i.e it can be rewirtten)

Yup, the above should do the trick.

Also,  After that what are the setting in code-composer to upload proramm in flash (not permamently i.e it can be rewirtten)

You can reprogram, there's no setting as such. You can program to flash multiple times.

I added my file to the above said flash pramm with few lines I added in it

But following errors are comming in it

line 139: error:

Please guide me to resolve it

Try this cmd file: 3630.F28069.zip

file is asking password

It is asking password

Here's the file and the password is "space" (press the a single space bar)

Dear Sir

Again same error is comming

Files/ti/controlSUITE/device_support/f2806x/v100/F2806x_common/cmd/F28069.cmd", line 139: error:

error: errors encountered during linking; "Example_F2806xFlash.out" not built

Ashutosh, lets take this in an easier way: please import the flash example project to CCS. Then try replacing your code with the one already present. Don't simple copy and paste but check everything.

Regards,

Gautam

Dear Gautam

I had resolved the problem by doing below said changes to cmd file

RAML2       : origin = 0x008C00, length = 0x001400     /* on-chip RAM block L2 */
   /*RAML3       : origin = 0x009000, length = 0x001000      /* on-chip RAM block L3 */

As RAML2 was previous only 400 it was exceeding its limit

Dear Gautam

I am now having different problem

First time when I load the programm in flash it works smoothly

However, when it is restarted it takes garbage value shows absurd result.

Also If I use different laptops to upload the prorgamm in control stick ram it dosent work it shows garbage values.

Why is it sooo

However, when it is restarted it takes garbage value shows absurd result.

Absurd result? If you're talking about the variables having garbage values after restarting then yes they'll have garbage values or if initialized to zero they'll have 0 as initial value. After restarting all the variables and result registers go to their reset values. Only the .out file ie the executable file is stored in flash and the variables values. If you want to store variable values and results in flash then there's a technique called "Emulation of EEPROM in FLASH"

Gautam 

Dear Sir,

Can I upload directly .out file using code composer

Please guide me

You can use CCS Uniflash to load only the .out file.

Dear Sir,

A have one funny experince with control stick 28069

I am using code composer V4

The DSP was working fine and also the DSP was controlled very nicely when I was using my Dextop PC. (program is loaded in RAM)

However When I uploaded the same programm  the ADC values in result register were showing absurd values. Then I tried with Flash, first time it was working when I controlled from PC, but when the same DSP was made to work independely without code composer control ( as the proramm was loaded in flash) it showed absurd results.

Can u explain me why it is so.

Now also if I am operating from same PC it is working fine, with  proramm loaded in ram.

That's very odd, Ashutosh! This shouldn't happen; are you sure the program loaded onto your flash is valid one?

Regards,

Gautam

While loading the programm in flash I am observing error

Please guide

This is wrt F28069 or F28027?

Hello Ashutosh,

I strongly recommend you to use the latest version of F2806x example (not v100, it is too old as it is first version and be sure many bugs!)

Please use C:\ti\controlSUITE\device_support\f2806x\v136, and please send again the thread in new thread when you have problem using this version.

Best regards,

Maria
