Good Afternoon everyone,

I am currently trying to flash some code into the flash memory of the TMDSCNCD28335. As such, I am currently trying to use the BlinkingLED example on the Resource Explorer. I have noticed that there is also an example on flashing on the Resource Explorer as well, but I have not had any successes on trying to merge the code together.

I have also taken notice of this chunk of code :

memcpy(&RamfuncsRunStart, &RamfuncsLoadStart, (Uint32)&RamfuncsLoadSize);

which, copies time critical code and flash setup code into the RAM of the device that I am using. However, once I start building and loading the code in, this error occurs :

C28xx: File Loader: Verification failed: Values at address 0x04000@Program do not match Please verify target memory and memory map.

I have searched online for details and more information on memory mapping, but am unsure of where and how to begin. Any help would be very very much appreciated

I can think of two things right away that can help:
1. C2000 Archived Workshops - F28335 multi-day workshop: processors.wiki.ti.com/.../C2000_Archived_Workshops
2. C28x Compiler - Understanding Linking: processors.wiki.ti.com/.../C28x_Compiler_-_Understanding_Linking

Hopefully, that helps.

Hi, apologies for the late reply. It has been a couple of busy weeks for me. I have read through the links that you have given, however, the flash option is not available in the menu that contains debug as well. I am also unable to follow the instructions in the youtube video that gives an insight into flashing programs into the flash memory. Erasing the data in the flash memory is working for me, however, when flashing new data in, the memory map issue always appears. Sorry for any inconvenience caused!

Best Regards,
Zen

I have also tried the example on flashing as given by the Resource Explorer, however, the issue with the memory map error occurs as well.
