LPC55S69JBD100E - SWD, JTAG and Flash programming

Laks489 — Fri, 24 Jan 2025 06:55:39 GMT

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

Hi ,

Does the NXP-LPC55S69JBD100 support OTA updates through bootloader when connected to the WM02C (nRF7002) via SPI? Please explain the OTA update process.
