MIMXRT1060_SFDP_QSPI.cfx Source Code

chadgraham — Thu, 22 Jul 2021 18:23:15 GMT

Hello,

I am trying to resolve an issue where I cannot add a second QSPI to the RT1060 Dev Board. One of the open questions relates to the MIMXRT1060_SFDP_QSPI.cfx and I'm looking for the source code.

Side note:

I found the iMXRT1050_QSPI example, but the project actually fails when you test it... I even tried it on a 1050 dev board. I do not have any faith that the example is even usable in this state.

I'm using MCUXpresso 11.3.1 and the 2.9.3 SDK

Hello @chadgraham,

Could you explain how are you modifying the EVK to add the second memory? By default the EVK has the QSPI connected but the FlexSPI channel connected to the HyperRAM is the same.

Hello Alexis,

We connected the second QSPI device to the same data bus as the existing QSPI device and added a wire mod to grab the proper chip select signal; All signals are assigned to the FlexSPI port.

Hello @chadgraham,

To use a second QSPI, you would need to connect it to the other FlexSPI channel and the code still would boot from the FlexSPI channel that the memory is connected but if need it after boot the code could be executed from the second QSPI. Also for this you would need to modify the boot config files, I will suggest to check the following app note Implement RWW on i.MX RT Series (nxp.com)

Also, the file that you're looking for is in the following path: path: MCUXpressoIDE\ide\plugins\com.nxp.mcuxpresso.tools.bin.win32_11.3.0.202103301458\binaries\Flash

Hi Alexis,

I'm actually looking for the source code so I can modify the .cxf file. I am only able to find a limited number of flash drivers in the folder.

Hello @chadgraham,

Unfortunately, these example drivers are the only ones available but as I previously mention, the process to add a second QSPI would be as the app note mention.
