Need Support for Firmware Update 453-00052R (BL5340)

[sathiya]

We recently purchased the module 453-00052R from Digi-Key and have successfully implemented it into our project. The design is complete, and we are now attempting to flash the firmware using the NRF5340-DK board via the debug port (P19).

While the code loads successfully, we are not observing any activity on the GPIO pins of the 453-00052R (BL5340) module. We are currently using a sample code that simply blinks an LED, which works without issues on the NRF5340-DK board, but does not produce the same results with the 453-00052R module.

Hi

Do your module include a external crystal? If no try to add the following Kconfig option

CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y

If you are using MCUboot  you also need to add it to mcuboot.conf

Hi, 

The firmware update has been successfully resolved, and the basic functionalities, including the context menu, firmware updates, LED blinking, and debugging, are now working properly.

However, we are currently facing an issue with SPI read and write operations. When attempting to read data, we encounter a hard fault error.
