Description
The default bitstream is loaded from OS not from u-boot. Reasons:
- Different banks have different (software - controlled and regulated) voltages and they need to be set up before loading.
- voltages are set by the software through i2c
Bitstreams paths
- /usr/local/verilog/
| name | description |
|---|---|
| x393_parallel.bit | for 5MPix sensor with parallel interface + SATA |
| x393_hispi.bit | for 14MPix sensor with serial interface + SATA |
| x393_sata.bit | SATA only |
| x359.bit | for external MUX 3-1 board |
Init
- /etc/init.d/init_elphel393
...
$CONFDIR/init_elphel393.py "{\"usb_hub\":1, \"ip\":1,\"imgsrv\":1, \"autoexp_daemon\":1, \"autocampars\":1, \"sata\":1, \"gps\":1, \"eyesis\":0 }"
...
- in this line the extra init procedures are listed, to disable/skip certain procedure set 0, to enable - set 1
- everything is done in /etc/elphel393/init_elphel393.py which runs other scripts.
- the bitstream is loaded by autocampars or sata (if autocampars is skipped)
