RT1064 | issues with second stage bootloader

Hello team,

My customer has the following issue. please see the details below:

System - Developing second-stage bootloader with RT1064.
Need to burn bin image from SD card to Winbound internal flash from 0x70010000 to 0x70400000.
All bootloader code is linked to RAM.
Using “How to use the RT1064 on-chip flash as NVM” application note from NXP community forum https://community.nxp.com/t5/i-MX-RT-Knowledge-Base/How-to-use-the-RT1064-on-chip-flash-as-NVM/ta-p/1123381
Custom LUT commands array edited to fit W25Q32JV flash.
Successfully reading vendor_id throw flexspi2 and getting 0xEF as expected.
Successfully reading STATUS REGISTER.

The bug is when I’m trying to enable write to flash using flexspi_nor_write_enable() func from flexspi_nor_flash_ops.c provided by MCUxpresso SDK.

SPI timeout configuration .AHBWriteWaitUnit = kFLEXSPI_AhbWriteWaitUnit512AhbCycle

Still getting error kStatus_FLEXSPI_DeviceTimeout = 7002.

Could you please advise back?, Thanks in advance

KR,

Shai

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
To provide the fastest possible support, I'd highly recommend you refer to the FOTA solution to implement the SD card OTA.
Have a great day,
TIC
