[edit] Contoh Burn EEPROM RFX di USRP1 ke 900MHz

Untuk burn EEPROM RFX RX 900MHz

cd /usr/local/share/uhd/utils
./usrp_burn_db_eeprom --id=0x0025 --unit=RX --slot=A
./usrp_burn_db_eeprom --id=0x0025 --unit=RX --slot=B
./usrp_burn_db_eeprom --id=0x0029 --unit=TX --slot=A
./usrp_burn_db_eeprom --id=0x0029 --unit=TX --slot=B

Atau satu per satu

cd /usr/local/share/uhd/utils
./usrp_burn_db_eeprom --id=0x0025 --unit=RX --slot=A

[edit] Catatan Untuk RFX Board Lama

Untuk RFX board lama kita perlu melakukan:

  1. Disable the daughterboard clocks. Move R64 to R84, Move R142 to R153
  2. Connect the motherboard clocks. Move R35 to R36, Move R117 to R115

These are all 0-ohm, so if you lose one, just short across the appropriate pads
