MCIMX93 debugger firmware

[TuanLam]

Hello! I am currently developing firmware for the I.MX93 board, on the LPC55S69 chip. I only have the KIT, a power source, and a USB-C cable. Can I debug on the LPC5569 chip with these, or do I need to use a JTAG port?

Hi,

Pls check your schematics, especially, check if the SWD port of LPC55S69:SWDCLK(PIO0_11), SWDIO(PIO0_12) and Reset to a connector so that you can use the Multilink Universal device from PEMicro or the NXP MCU-Link or MCU-Link Pro device to download and debug.

Hope it can help you

I see in the schematic that there is support for JTAG connectivity, and I have configured it according to the instructions. If I'm correct, pin RC_nSEL should be at 0V to establish a JTAG connection, but currently, I still don't see RC_nSEL at 0V.

Hi,

For the LPC5569, if you want to download application code to on-chip flash of LPC55S69, you have to use SWD port, the JTAG port of LPC55S69 is only for boundary scan function.

Do you want to use i.mx processor to write SWD port to manipulate the on-chip flash via SWD?

So, does that mean the USB REMOTE DEBUG block cannot be used to debug the MCU inside the CPU, and we have to use the JTAG circuit for debugging?

Hi,

As I said that the LPC55S6x uses SWD port instead of JTAG for on-chip flash operation.

Pls check if the FT4232H support SWD.

Thank you very much.

I am currently facing an issue with installing the SDK on MCUXpresso IDE.

I generated the SDK for the IMX93 board on the website.

After downloading the SDK, I tried to drag the card into the Installed SDK tab, but encountered an error as shown in the picture. Can you please help me with this?

Hi,

Unfortunately, I only support LPC family, I am not sure if you can use MCUXPresso tools to compile/link SDK example for i.mx family.

This is i.mx forum, pls create a ticket for i.mx family and ask if the MCUXPresso tools supports SDK for i.mx family
