Other Parts Discussed in Thread: C2000WARE,

Tool/software: Code Composer Studio

Hi,

We can't boot from flash with following steps.

step 1. Import fcl_f2838x_tmdxiddk_cpu1 project

step 2. Modify iddk_servo_2838x_flash_Ink_cpu1.cmd

//.data : > RAMLS6 | RAMLS7

.data : > RAMGS0

step 3. Adding a dummy const array

name	origin	length	used	unused
RAMGS0	0000d000	00001000	00000e45	000001bb

step 4. Boot from flash - PASS

step 5. Increase the array

name	origin	length	used	unused
RAMGS0	0000d000	00001000	00000e4b	000001b5

step 6. Boot from flash - FAIL

However, USB debug can boot normally. Is there any size limit for the .data?

If it works with USB boot mode then i think the image is correct.

Did you compile the project with RAM configuration or Flash configuration ?

How did you program the image on to flash ? what are the positions of boot select pins ?

Hi Baskaran,

Did you compile the project with RAM configuration or Flash configuration ?

- Build icon -> F2838x_FLASH

How did you program the image on to flash ?

- Flash icon -> fcl_f2838x_tmdxiddk_cpu1

what are the positions of boot select pins ?

Mode	Switch Position 1	Switch Position 2	Boot From
03	1 (left)	1 (left)	Flash/USB

what is the code start address...the beginning address of your application.

other option is try to connect to ccs and check what is the status of the device.

Hi Baskaran,

ENTRY POINT SYMBOL: "code_start" address: 00080000

The beginning address should be "main", I add a while loop to trigger LED after "Disable global interrupts."

origin	length	input sections
00083aac	0000002e	main.obj (.text:main)

Do you means try to use Debug Mode to check? Device boot normally in Debug mode.

the beginning point of your application is not Main().

It will be cinit code which starts with codestart or entry_point. Check your map file for these symbols and jump to corresponding address.

Hi Baskaran,

Which means fcl_f2838x_tmdxiddk_cpu1 project in C2000Ware MotorControl SDK has wrong codestart or entry_point?

I've compare two map file (OK & Fail), and address were same.

section	page	origin	length
codestart	0	00080000	00000002
.cinit	0	00090000	00000348

Code start is correct in the SDK and it pointing to 80000.

You need to connect debugger (CCS) and see where the PC is pointing to debug further.

Are you using custom board or TI control card/ launch pad ?

Hi Baskaran,

We're using TMS320F28388D controlCARD (F28388D controlCARD evaluation module)to develop.

ok, i dont see anything wrong with the initial setup. You need to connect debugger and try to get better understanding of whats going on.

Hi Baskaran,

I've check in debug mode. It start from main.

Could you replace fcl_f2838x_tmdxiddk_cpu1.c and try to mark/add some items in SemiSlave_objdict array?

The LED will blinking, if device is running. Thanks

fcl_f2838x_tmdxiddk_cpu1.c

Hi Tony,

Do you have codestartbranch.asm included in your project? If not, please include and see if that clears the issue.

If you application works in debugger connected scenario but not in standalone mode, then one reason might be watchdog.

When debugger is connected, watchdog is disabled by gel.

In standalone mode, if the application fails with increase in a buffer size, it might be that the watchdog expired while the cinit routine is initializing the global variables. Codestartbranch.asm has code to disable watchdog in it. Please check.

Thanks and regards,

Vamsi

Hi Vamsi,

Device can boot after disable watchdog.

Thanks for your help!
