First, some background. I am updating a project and hardware which allows updates over the CAN bus.I updated to the latest CCSv5 5.2.0.00069 and v6.1.0 compiler and FlashAPI 3.10 and rts2800_fpu32.lib. All the code loads to FLASHA and runs from SARAM. I'm debugging with JTAG.
With this setup, I now get a bunch of linker warnings (which I ignored). With previous tools I had a clean compile.
#16002-D build attribute vendor section TI missing in "../Flash28335_API_V210.lib<Flash28_ClearLoop.obj>": compatibility cannot be determined XXXX C/C++ Problem
My code changes included:
FLASH_ST FlashStatus; // Flash erase status.
if (STATUS_SUCCESS == status)
which was failing with status=13 which corresponds to STATUS_FAIL_INCORRECT_PARTID.
After getting this fault, I made some code changes and now I get the following when I try to debug"
C28xx: Flash Programmer: Warning: The configured device (TMS320F28335), 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, check if device is unlocked and recalibrate.C28xx: GEL Output: ADC Calibration not complete, check if device is unlocked and recalibrate.C28xx: Flash Programmer: Error erasing flash memory.

My Properties/General selects the Device Family: C2000, TMS320F28335 which matches my hardware.
If I connect JTAG to an eZDSP board it connects and downloads fine.
Did I inadvertently lock my device? How do I get rid of the link warnings?
When I change the boot mode of the eZDSP to "Branch to check boot mode" and don't have it erase anything during the load. (run from RAM) I can get some code loaded and have it run. I can also look at the CSM registers and the memory window on FLASHA shows it is not secured and completely erased. (including CSM_PWD locations)
So I don't think I have bricked my hardware. However, if I try to erase a flash sector I get the message about:
C28xx: Flash Programmer: Warning: The configured device (TMS320F28335), does not match the detected device (). Flash Programming operations could be affected. Please consider modifying your target configuration file.
This is starting to smell like a tool problem. How do I figure out what device CCSv5.2.00069 is detecting???
When I run SDConfigEx:
* Checking emulator/eZdsp scan connection
** Emulator Test ** $$ EmuProductName=XDS510USB $$ EmuPortAddr=0x510 $$ EmuPortMode=USB $$ ProductId=510 $$ ProductVersion=84 ** Emulator Scan Test -- Found JTAG IR length of 38 -- Found 1 JTAG device(s) in the scan chain
But I don't know how to see the scan test values (and this isn't necessarily the same method used by CCS)
In reply to Jerry Trantow:
As a sanity check on the flash settings, I ran the On-chip flash frequency test and I see the 10khz on the GPIO pin but it only toggles for approximately 35msec???
I'm also confused by CSM. From my reading of the app note, I should see zeros if I try to read flash. However, when I reset using CCS I see the CSMSCR.SECURE=0 and the flash looks erased. All FFFF's. However, if I do a restart the flash memory shows up as all 0's and the CSMSCR.SECURE=1 which makes it look like I bricked my boards???
What's the definitive test (via CCSv5) for whether a TMS320F28335 is CSM locked?
I had a similar problem with a TMS320f28027. After the update of my CCS4.2.4 I`ve got also the message:
The configured device (TMS320F28027), does not match the detected device (). Flash Programming operations could be affected. Please consider modifying your target configuration file.
After I exchanged my license I had some problems with the linker. With the message:
warning: creating output section ".xxx" without a SECTIONS specification
There where an additional *.cmd-file in my project. I don`t know why.
After I deleted this file and linked the "DSP280x_Headers_nonBIOS.cmd" everything worked fine.
I`m really not an expert in CCS and I don`t know why the way I described work, but perhaps you can also go this way.
