| == e1-tracer Gateware |
| |
| The e1-tracer _gateware_ is where pretty much everything happens, |
| from the E1 Line Interface Unit to the E1 Framer/Deframer, the |
| picoRISCV soft-core running the [[firmware]] as well as the USB |
| device peripheral talking to the host PC. |
| |
| The gateware is stored in binary form on the device-internal |
| non-volatile memory (SPI flash). It is field-upgradeable via USB. |
| |
| As an OSHW project, all of it is available in source code format |
| at https://git.osmocom.org/osmo-e1-hardware/tree/gateware/e1-tracer |
| |
| Please use `git clone --recursive` when cloning the git repository |
| so you get all of the sub-modules for the various soft-cores. |
