KV31F Tower havings issues with PE and Flash driver combo

Question asked by Steven Neves on Dec 2, 2015

I have run both the flash_example and flash_demo and simply tried replicating this logic within a new project (for a bootloader) using Processor Expert.  I am aware of the demo/example using the bare metal platform library rather than PE but that appears to be the only difference.  My main issue appears to be centered around:


g_FlashLaunchCommand = (pFLASHCOMMANDSEQUENCE)RelocateFunction((uint32_t)__ram_func , LAUNCH_CMD_SIZE ,(uint32_t)FlashCommandSequence);


Whether I'm calling FlashEraseSector, FlashReadResource, FlashProgram, etc.  They all call:


ret = pFlashCommandSequence(pSSDConfig);


This always returns 0x20 (FTFx_ERR_ACCERR)


Attached is my test project, at this point I really can not tell a difference between the demo and my test application in regards to utilizing this driver.


Thanks in advance.
