Tool/software:
Hello Team,
I am using flash sector number 13 for EEPROM emulation. The EEPROM emulation code works as expected on CPU core 1. However, the same code does not work on CPU core 2.
I am trying to copy data from GSx RAM to EEPROM but it is not happening. I have debugged the issue and found that the bank pointer, page pointer and write buffer are being set as expected. Additionally, the Flash API function Fapi_issueProgrammingCommand is returning a success status.
I have checked with another sector, changed the page size, buffer size, and data, but I am still unsuccessful on CPU core 2. In all the scenarios, it is working on CPU core 1.
I am using below linker file for both cores. All operations are working on CPU core2 except EEPROM.
Is there a permission / ownership issue? Or, am I missing any necessary configuration for Core 2? Could you please help me with this?
