RM48L952, Rev B: Load program Error in CCS5.2.1

I am still waiting for a response.... thank you in advance!

Hi Flurin,

Please double check your cmd file to make sure the RAM size is 192K (for RM48LS55x) rather than 256k (for LS95x), and the Flash size is 2MB (for LS55x) rather than 3MB (for LS95x). It would be helpful if you post the compiler warning message.

Hi QJ

Thank you very much for your answer. Unfortunately, in my previous post, is misspelled the CPU-Type. The CPU on my board is the RM48L952-PGE, Rev B.

I checked the linker cmd file, it seems to be correct. (256k Ram and 3MB Flash)

When compiling and linking the program, i do not get a warning or error-message.

When loading the program, i get the following message in the console window:

Loading the program with nowFlash works

Loading the symbols from the IDE (setting load symbols only in the debug configuration) allows me to debug without problems

I therefore assume, that the flash-programming algorithm that CCS uses is not suitable for the Rev B?

Hi Flurin,

I think your question is similar to this one:

https://e2e.ti.com/support/development_tools/code_composer_studio/int-code_composer_studio/f/90/p/204939/726844.aspx?Redirected=true

It looks like a bug in CCS5.2, and will be fixed in CCS5.3

Hi QJ

Thank you for your answer. Unfortunately the link you provided does not work. Could you post it again? Thank you very much!

Hi QJ

I just downloaded CCS 5.3 and tried to download the program. The problem is the same, but the message is the following:

CortexR4: GEL Output:     Memory Map Setup for Flash @ Address 0x0CortexR4: Flash operation timed out waiting for the algorithm to complete. Operation cancelled.
CortexR4: Trouble Halting Target CPU: Error 0x80001822/-1141 Fatal Error during: Memory, Execution, Timeout, Target,  Processor communication timeout. It is recommended to RESET EMULATOR. This will disconnect each target,   perform an emulation reset, and then reconnect each target. Power cycle the target board before continuing.  
CortexR4: Warning: Error 0x40000108/-1169 Warning during: Break Point, Cache,  Error during instruction cache flush
CortexR4: GEL: File: C:\SVN\solarmax_xt\MP\tools\Ccs5\Project\solarmax_xt_mp\Debug\solarmax_xt_mp.out: Load failed.

Do you have an idea what could be wrong?

I have the same problem too with CCS5.3

I can not load the code when I set RM48L952

Hello,

In CCS5.3, please select the target connection at your project property -> CCS Genera -> Main -> Device -> Connection, and check "manage the project's target configuration automatically". What kind of JTAG emulator do you use?

Thank you for the tip, but activating the check box does not solve the problem.

Any other tip?

It seems really to be a communication problem. After the message "CortexR4: GEL Output:     Memory Map Setup for Flash @ Address 0x0" nothing happens for several seconds, then the timeout occurs and the rest of the error message is displayed.

Using the SpectrumDigital XDS510 USB Plus

Hello,

I'm looking for the reason why I cannot load a program to my RM48L952PGE target with XDS510USB Plus from within CCS Studio 5.3.0.00090

If I select the 952 which is the one I have on my hardware it does not work.

If I select the target 950 as seen in the screenshot here the load works!

Any ideas?

Hello John,

Thank you very much for your explanation and your workaround.

Tested and it works!

Roger
