Hello,

I have a question about the internal Flash of IMXRT1064.

How do I read / write to the SIP 4M Flash Memory described on page 1426 of the i.MX RT1064 Processor Referenc Manual? Please let us know if there is anything useful such as a sample or a linker file.


Thanks for any help, thank you.

T.Y.

Hello, 

The on-chip 4MB memory is connected to the RT through the FlexSPI2 interface. So, accessing this memory it's the same as if you wanted to access an external flash memory. The memory that comes within the package is a Winbond W25Q32JV. For more details about the memory, please visit http://www.winbond.com.  Additional to that, within the SDK you will find two examples named flexspi_nor_polling_transfer and flexspi_hyper_flash_polling_transfer. These two memories are also connected to the RT through the FlexSPI interface, so the procedure to follow is the same if you want to access the on-chip memory. 


Have a great day,
Victor

Hello yamakatb@eng.ryosan.co.jp 

Please refer to the following community document, here you will find a detailed explanation of all the modifications that you need to make to one of the SDKs examples to use the on-chip flash as NVM. 

RT1064 use on-chip flash as NVM
