Qspiflash erase

Hi,

I am using MIMXRT1170 Evk. I am working on multicore. The SDK i use is multicore hello world example. I want to erase 4sectors(16kb) starting from address 0x30000000 in cm4 so I want to erase the code in cm7 from cm4. I used ROM_FLEXSPI_norFlash_erase so i took advantage of rom_api SDK. But the function returns 7001 error. As i understand there ıs an align for address. Which address should i write to erase the code at 0x30000000?

is what i want to do possible?

Can you help me?

Thanks for your helping,

Best regards,

Hi mehmetkaradag,
Thanks for your questions. It seems you want to erase sectors Nor flash via FLEXSPI, to avoid some specific details, I strongly recommend that you refer to "SDK_MIMXRT1170-EVK\boards\evkmimxrt1170\driver_examples\flexspi\nor\polling_transfer\cm4\readme.md" firstly.
Thanks again.
