Hello community.

 

I'm trying to debug iMX8MP-CM7 with LPC-Link II.

LPC-Link II boot with JLink firmware and host use JLink_Linux_V760g_x86_64.

I already patched jlink driver patch informed the following thread.

<https://community.nxp.com/t5/i-MX-Processors/How-to-debug-iMX8MP-CM7-via-JTAG/m-p/1278452>

 

In my environment,

If Linux BSP boot process stopped on the u-boot and try to connect JLinkGDBServer.

It is OK to connect JLinkGDBServer and run arm-none-eabi-gdb correctory.

 

But if BSP boot to kernel login, if try to connect JLinkGDBServer it will be reboot CA53

and restart boot process.from u-boot.

 

How can I avoid this problem?

 

Best regards,

Ishii.
