RN-ISP-UM-1.1
FLASH LOADER UTILITY
It is sometimes convenient to load a binary image without installing and using the SDK. With the flash loader utility, you can
flash the firmware onto the module using a PC. To use the flash loader utility, you must have the RN-ISP and a target
board with a 16-pin debug header.
To set up the hardware, first, connect the target board to the RN-ISP using a 16-pin ribbon cable. Then, connect the
RN-ISP to the PC using a USB cable.
Before using the flash loader utility, you must first locate the DMA COM port associated with the utility. The DMA port is
usually the second highest of the four COM ports that are created for the ISP. For example, if the COM ports are labeled
COM3, COM4, COM5, and COM6, COM 5 is the DMA port. See Figure 13.
Figure 13. COM Ports in Device Manager
!
If the COM port is higher than 10, re-assign the DMA COM port to a number below 10 using the device manager. For
example, to change COM31 to COM3 in Windows, perform the following steps:
1. Double click COM31 in the device manager under Ports (COM & LPT). The USB Serial Port (COM31)
Properties window opens. See Figure 14.
