1. In our project, we are using the NXP controller LPC55S69JBD100E. Is SWD and JTAG both required for programming?
2. Can you provide an explanation for the flash programming?
Hi Laks489,
LPC55S69 uses SWD interface to debug and program. Jtag is for boundary scan but can't work for debug and program.
In ISP mode, we can also use USB, UART, SPI, I2C program Flash. But we can't use these peripheral debug.
Hope this helps,
Jun Zhang
