Jumper Set to Program Mode Selection
No jumper 5-Vin Bias from J31 external
Jumper shorted 5-Vin Bias from USB, 5 Vin from J31 must not be connected
6.1.8 Onboard Dynamic Load Selection [S3 for CPU, S2 [Upper) for GPU, S2 (Lower) for VCCIO]
The onboard dynamic load can be set by S2 and S3.
Default setting: Push S2 and S3 to OFF position to disable the on board dynamic load.
Table 9. Onboard Dynamic Load Selection
Switch Set to Dynamic Load Selection
Push S3 to ON position Enable 32-A onboard dynamic load at CPU
Push S3 to OFF position Disable 32-A onboard dynamic load at CPU
Push S2 (upper) to ON position Enable 19-A onboard dynamic load at GPU
Push S2 (upper) to OFF position Disable 19-A onboard dynamic load at GPU
Push S2 (lower) to ON position Enable 10-A onboard dynamic load at VCCIO
Push S2 (lower) to OFF position Disable 10-A onboard dynamic load at VCCIO
