interrupt signal when performing world switch on GICV3/4

We have a question on the interrupt signal when performing world switch. Suppose the CPU is running in secure world (TEE). An interrupt(Non secure Group1) is generated from REE. With SCR_EL3.FIQ...

STM32F103 - Switching from JTAG to SWD

Hello, I am working with an STM32 board, a JLink EDU and STM32Cude IDE and trying to understand the SWD protocol better. I am observing the SWD signals on an Oscilloscope and came across something that...
