MCUXpresso Secure Provisioning Tool - Mass Erase by UART

[Lukas_Frank]

Hi Dear Authorized,

I have some cards which is lost debug connection. I am not able to connect my cards. These are specifically designed cards which uses RT1024 and RT1064. I am trying to recover them by MCUXpresso Secure Provisioning Tool. I want to use it by using UART.

Firstly, I tried this recovery operation with EVK a setup below. I am able to debug my card with this setup. I mean USB connections work but MCUXpressoSPT is not detecting my EVK. I don't know the official way of using UART SPT Mass Erase.

Could you direct me to the official way to do this?

My Setup and Details:

• LPUART1
• FTDI Module
• PmodRS485
• Type-C USB Convertion HUB for Mac.
• MCUXpresso IDE v11.8.0
• MCUXpresso Secure Provisioning Tool v7

Thanks and Regards.

I find extra informations below:

You can use above configurations with simple RS485-Serial connection.

RT1024 supports UART1-UART2 according to technical data.

RT1064 supports only UART1 according to technical data.

I am able to connect just over UART1 for both RT1024 and RT1064.

Thanks and Regards.
