| em100: EM100-Pro command-line utility |
| |
| This tool supports using the Dediprog EM100-Pro [1] in Linux. It supports both |
| the original version and the new -G2 variant. |
| |
| The 'em100' device provides a way to emulate a SPI-flash chip. Various |
| connectors are available to allow it to take over from the in-circuit SPI chip |
| so that the SoC sees the em100's internal memory as the contents of the SPI |
| flash. Images can be loaded into the em100 over USB in a few seconds, thus |
| providing a much faster development cycle than is possible by reprogramming |
| the SPI flash each time. |
| |
| Example: |
| ./em100 --stop --set M25P80 -d file.bin --start -t -O 0xfff00000 |
| |
| Major features provided by the tool include: |
| |
| - Set the chip being emulated (the tool supports about 600) |
| - Adjust the state of the hold pin, which supports overriding the internal SPI |
| - Use of several em100 devices, distinguished by their serial number |
| - Terminal mode, allowing the SoC to send messages |
| - Output a trace of SPI commands issued by the SoC |
| - Reading / writing em100 firmware (dangerous as it can brick your em100) |
| |
