Hi! I am on a project of usb dongle.I programed the dongle and lost the bootloader pre-programed in the factory.And I have a SPI downloader,I want to download the bootloader so that I can test my PC downloading application which program the dongle through USB.Where I can get the hex file?

Hi Jinss,

You can find the hex file in nRFGoStudio folder if you have installed it:

C:\Program Files (x86)\Nordic Semiconductor\nRFgo Studio\hex

Hi, I installed the nRFGoStudio and I find the folder which contains the hex files.There are 6 hex files which 2 of them's name contain string "24lu1p".One's name is "boot24lu1p-f32.hex" and another file name is "nrf24lu1p_rf_test.hex".Does the string "f32" mean 32KB flash? which one is the 16kB-flash chip's bootloader?
