KV31F Tower havings issues with PE and Flash driver combo

stevenneves — Wed, 02 Dec 2015 18:11:48 GMT

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.

EDIT:

Hardware: TWRKV31F120M

IDE: KDS 3.0

SDK: KSDK 1.3

Hello Steven Neves:

Flash erase/program operations are not possible in HSRUN mode (maximum frequency). Try setting Clock Configuration 4 in your project:

Then generate code, build and try again. I hope this helps.
