Buard EEPROM
Older RFX boards require modifications to use the motherboard oscillator.
 
If this is the case, UHD will print a warning about the modification.
 
Please follow the modification procedures below:
 
Step 1: Disable the daughterboard clocks. Move R64 to R84, Move R142 to R153
Step 2: Connect the motherboard blocks. Move R35 to R36, Move R117 to R115
 
These are all 0-ohm, so if you lose one, just short across the appropriate pads
 
Step 3: Burn the appropriate daughterboard id into the EEPROM

* <args> are device address arguments (optional if only one USRP is on your machine)
* <slot> is the name of the daughterboard slot (optional if the USRP has only one slot)

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
