The i.MX RT1010 Evaluation Kit cannot erase flash memory contents

[Omar_hong]

Hi NXP,

    I used the flexspi_nor_enable_quad_mode function from the NXP MCU SDK to modify the flash register, but after execution, the flash can no longer be erased. Relevant information is as follows.

I tried using flexspi_nor_enable_quad_mode to modify the flash SR2 value to 0x00, and then changed it to 0x02. However, after execution, the flash could no longer be erased.

By the way, I have enabled both OTFAD and HAB. Given the current situation, is it possible to resolve this using the SPT tool?

note: Currently, the flash editor in SPT can only read, but cannot write or erase

Hello Omar,

Currently, the flash editor in SPT can only read, but cannot write or erase

could you please provide information if you used custom FCB or if you used the simplified configuration to erase the Flash? The custom FCB (where did you get it from?) might be read-only (not having RW/Erase configuration in LUT).

The simplified Flash configuration should allow you to erase the flash. Unless you configured the Flash itself somehow.

Regards,

Libor

Hi @liborukropec 

  I think I was use the simplified configuration

Before I use this function" flexspi_nor_enable_quad_mode" can still read, write and erase normally. 

I only wrote 0x00 to status register 2.

 Unless you configured the Flash itself somehow.

=>If so, do you have any suggested solutions?

Unfortunately no, I'm not expert in this topic. I'd recommend to consult with the documentation of the memory vendor.

Hi @liborukropec 

    Understood. I’ll follow up with the supplier’s FAE for confirmation.
