5.2 Download ASCII Pass-through Firmware

The

img-passthru-g3-ascii-fcc

bundle can be downloaded to the SM2400-EVK2 FCC module using the

SM2400Control GUI as described in the SM2400-EVK User Guide.

If an FTDI cable is used for downloading, pin 1 (3V3) and pin 2 (Mode1) of header P1 must be connected via a

jumper to pull the Mode1 pin high for downloading. This jumper is shown in Figure 6 below. After the download is

complete, remove the jumper and power cycle the SM2400-EVK2.

If a mini-USB cable is used for downloading, there is no need to manually control the Mode1 pin because it is con-

trolled by the CP2110 on the SM2400-EVK2 base board.
