| 10 | h2. Current stack |
||
| 11 | |||
| 12 | * The hardware is currently not documented, only 2 prototypes exists and have been half hand-wired. They are currently based off iCEBreaker and iCEBreaker-bitsy iCE40 dev boards. ( https://github.com/icebreaker-fpga/icebreaker ) |
||
| 13 | * The gateware is temporarily hosted in the 'e1' branch of this repo : https://github.com/smunaut/ice40-playground/tree/e1/projects/riscv_usb |
||
| 14 | * The embedded software is in the same repository as above, in the 'fw' sub-directory : https://github.com/smunaut/ice40-playground/tree/e1/projects/riscv_usb/fw |
||
| 15 | * The userspace daemon that handles the USB communication is hosted at: http://git.osmocom.org/osmo-e1d |
||
| 16 | * The support for this daemon interface to the rest of the cellular stack is in a 'tnt/e1d' branch of the libosmo-abis repo : http://git.osmocom.org/libosmo-abis/log/?h=tnt/e1d |
