Can MfgTool2 load the flashloader using UART or USB-CDC?

Is it possible to use MfgTool2 to load the flashloader into a i.MXRT1064 using only the UART on the chip for boards that don't have a USB port. I know it can be used in the second stage where blhost is used, but getting to that stage without the USB seems impossible.

Hello Kcenov,

The manufacturing tool does only support USB port communication.

However, you may use the MCU Boot Utility tool (link below) as it does support UART communication to load the flashloader.

I hope that this information helps!

Gustavo

Hello Gustavo,

Thanks for the suggestion, but we need something more fixed-function as the people using it are not developers and it has to be simple. MfgTool2 was looking perfect and we are still going to use it for boards with USB. The user guide is misleading though, as it says it can be used with UART as well.
