Firmware Update

[sagar_prajapati]

Hello all,

I am trying to use secondary bootloader in IMX RT 1064 development board with default configuration in IAR Embedded Workbench. I have tried using SDK example by changing the linker file.Firmware is boot from QSPI Flash.BL_TARGET_RAM is defined as preprocessor. Will you please give some working example?

Hi Sagar Prajapati

Yes, as you mentioned, the secondary bootloader that we provide with the mcuboot is a RAM bootloader, and unfortunately, at the moment there isn't a flash resident bootloader for the RT families, you can implement this application, but you will need to place the "erase/write" code in the internal ram.

Using QSPI Flash on imxrt1060 EVK for booting and back-up storage 

RT1050 QSPI Flash Limitations 

Hope this helps.
Have a great day,
TIC

Hi Sagar Prajapati

If you enable USB or UART, you can use the ROM code that is in the RT10xx families, this code can be used along with the mfgtool tool or with the MCUbootutility to program your external memory.

One-stop secure boot tool: NXP-MCUBootUtility is upgraded to v1.4.0 

Hope this helps

But for this functionality, every time we need to enable serial download boot mode using switch. For custom hardware it is not proper way. We need something like ROM bootloader like after every power on reset it boots and coming in HID devices.

Hi Sagar Prajapati

You can enable serial download by default out of reset and after every power-on reset, it will boot from the ROM code with HID interface.

Hi Sagar Prajapati

If you mean how to enable the boot from the ROM code, it can be done with the GPIO (boot from GPIO) or you can use the boot from the fuses, so every time you have a reset, it will boot from the ROM code.
