The SPI flash programmer allows users to program the impOS for imp004m and imp005 into a SPI flash chip. You will need to copy the agent and device code from the git repository into your ImpCentral account and program it to the SPI Flash programmer.
Once the code is loaded on the device you will see the main menu on the display. Select between imp004, imp005 or private cloud and press ENTER. The device will start downloading the impOS image from the cloud and the screen will display the status. Once this is complete you can press ENTER to begin flashing your SPI flash chip. The SELECT button can be used to return to the main menu. If you are in the main menu you can program a SPI flash chip again without downloading the image by selecting the image that is already stored. The stored image is displayed at the top of the screen.
The SPI flash programmer has two buttons, SELECT and ENTER. SELECT is used to navigate the menu and ENTER is used to select the options.
The SPI flash programmer supports 8-WDFN, 8-SOP, narrow 8-SOP and has a 10 pin J-Tag connector for external connections. Identify which socket matches your SPI flash chip and insert the chip. If your SPI flash is already soldered to a board then use the 10 Pin J-Tag connector. The pinout is labelled on the back of the board. This pinout is labelled to match the Sparkfun Bus Pirate Cable.
The device has two toggle switches, Ext En and 3V3 Ext. The Ext En switch is used to enable the 10 Pin J-Tag connector. The 3V3 En switch will enable power to the 3V3 pin on the 10 Pin J-Tag connector.
A 3.5mm jack is available to use a footswitch in place of the SELECT button.
