IMXRT1064 Firmware Update Using ROMAPI

[irshadkn]

I am implementing a bootloader for IMX.RT1064. I'm using ROM API to erase and program the new firmware. I'm trying to erase the section after the bootloader and it is not working. When I tried erasing the sector that doesn't has the program, the erase API worked. Whether the sectors with the program is protected? Our goal is to implement a bootloader that can read the firmware from the external SPI flash and program to the internal flash.

Hi @irshadkn 

I hope you are doing well!

I do not think that you are getting some sectors protected. Could you provide me further details about your implementation?

For example : Memory addresses,  are you are using the ROM API functions to erase the RT1064's 4 MB QSPI flash in chip?, return values from APIs etc. Some code excerpt where the issue can be reproduced. 

Below some information that migth help.

In the RT1064 RM  (IMXRT1064RM)  page 261 , under this paragraph The following is a typical use case of the FlexSPI NOR API  we have an example of the NOR API. 

The RT1064 can only do XIP boot  from  RT1064's 4 MB QSPI flash in chip. 

Best regards,
