SLAU358Q September 2011 – October 2019
The MSP Gang Programmer can program target devices with an image loaded from an external SD card. To program from an external SD card, copy a binary file (".mspgangbin") created using steps described in Section 2.1.9 to the root directory of the SD card (preserve the original extension of ".mspgangbin"). If multiple binary files are present in the root directory of the SD card, the first one found is used (the first one found is not necessarily the first one alphabetically). To ensure that the desired binary file is used, verify that only one binary file with the proper extension .mspgangbin is present in the root directory. The name of the selected file is displayed on the LCD screen of the MSP Gang Programmer.
When the SD card is connected to the MSP Gang Programmer, internal memory is disabled and an image can only be read from the SD card. This mechanism has been deliberately implemented to aid in production because inserting an SD card to the MSP Gang Programmer leaves users with only one option for programming a target device and, therefore, less possibility for misconfiguration errors.
