Tool/software:
Hello All,
My development code size is increased and getting the following error.I tried to optimize code its helped some time .
I checked data sheet of TMDSCNCD28388D it seems i cant alter the linker file for additional memory allocation to fit code.
Is there any way i can use FLASH area instead of RAM area for flash.
Also currently iam using the inbuilt debugger XDS-10.
Thanks in advance
Narasimhaj
Hi Narasimhaj,
Can you show what the current memory allocation looks like for your program?
Have you used max available flash memory for this device?
Thanks and regards,
Charles
Hello Charles,
Thanks for the reply.
I am here by attaching the device_cmd.cmd file where the memory allocation for RAM and FLASH are available, i tried to modify these lengths, but during the building it reverts back to original values of length and addresses.

Have you used max available flash memory for this device?
Could you suggest me where i can change these configurations to adapt more flash area to accommodate higher code size.
Thanks and Regards
Narasimhaj
Hi Narasimhaj,
The generated .map file would do better to show the memory allocation for this device. There, we could see how much Flash memory is being taken and if some sectors can be used for further allocation.
To add more flash sectors for programming, you can modify this line:
CMD2.sectionMemory_text = ["FLASH1","FLASH2","FLASH3","FLASH4"];
to include FLASH5, FLASH6, ... for more flash memory space.
I will note that the origin error indicates that the sections stored in RAM are larger than available RAM space, therefore unused seen as 0x0. Can you use GS RAM instead for those allocations?
Also, when you are generating the project the error shows up in the RAM config only correct?
Thanks and regards,
Charles
Hello Charles,
Sorry for late reply,
Thanks it worked.
