RK806-1 Pinout Verification

flux

Fixed the RK806-1 terminal Pin Type assignments from the datasheet.
Key changes:
  • VCCx, VCCA, VCC11–14 → Power In
  • SWx, NLDOx, PLDOx, VCCIO → Power Out
  • VOUTx, FBx, PWRON, CS, CLK/SCL, VDC → Input
  • MOSI/SDA, MISO/PWRCRTL3, SYNC, SYNC_CLK, EXT_EN, RESETB, PWRCRTL1/2 → Bi-Directional
  • INT → Output
  • ePAD → Ground
I verified the updated properties and the part review checks show no unresolved terminal/property warnings or errors. Note: I only changed Pin Type as requested; the older Terminal Type metadata is still present but should no longer be the authoritative pin classification.

Search through all the pins of this part, see if there's invalid values like [Object Object]?

flux

I’ll inspect every RK806-1 pin property directly from the schematic and look for malformed values such as [Object Object] in pin names, pin numbers, pin types, descriptions, and related terminal metadata.

flux

I scanned all 69 RK806-1 terminals/pins.
No [Object Object]-style malformed values were found in the visible pin properties. The structured Symbol Pin Position values are valid JSON/vector data, not malformed text.
One thing to note: every terminal shows its internal Pins: entry as undefined, but the actual terminal metadata is present and valid: designator, pin number, pin type, section, group, and symbol position. The terminal review checks also returned no unresolved pin/property issues.

RK806-1 Pinout Reference Check
Scope
Compared the current RK806-1 Flux symbol terminals against:
  • Rockchip RK806 Datasheet Rev 1.3, section 2.7 Pinout Number Order.
  • FriendlyElec NanoPC-T6 reference schematic, sheet 15 Power-PMIC_RK806-1, U2200A RK806-1 QFN68.
Focus: buck regulator VCC / SW / VOUT / FB mapping that affects RK3588 PMIC wiring.
Result
The current symbol pin-number mapping for the buck-related pins matches the Rockchip datasheet and NanoPC-T6 reference schematic. I did not find a physical pin-number swap in the VOUT/SW/VCC/FB buck pins.
However, many Flux terminal electrical types are incorrect. In the RK806 datasheet, VOUTx pins are feedback inputs to the PMIC, SWx pins are switching outputs, VCCx pins are power inputs, and FBx pins are feedback inputs. The current symbol marks several of these as output, input, or powerIn inconsistently. This can mislead schematic wiring and ERC, even though the physical pin numbers are mostly correct.
Expected Buck Pin Mapping

Current Symbol Issues Found
1. VOUT pins should be PMIC feedback inputs
Datasheet descriptions say every VOUTx is an output feedback voltage input to RK806. These should not be modeled as PMIC power outputs. Examples from the current symbol:
  • VOUT10 pin 25 is marked Terminal Type output; expected electrical direction: input/feedback.
  • VOUT9 pin 67 is marked INPUT; direction is close, but should be consistently documented as feedback input.
  • VOUT5 pin 46 is marked INPUT; OK directionally but should be feedback input.
  • VOUT4 pin 24 is marked powerIn; expected feedback input.
  • VOUT3 pin 56 is marked powerIn; expected feedback input.
  • VOUT1 pin 49 is marked INPUT; OK directionally but should be feedback input.
  • VOUT7/VOUT8 are marked output; expected feedback input.
  • VOUT6 is marked powerIn; expected feedback input.
  • VOUT2 is marked INPUT; OK directionally but should be feedback input.
2. SW pins should be switching outputs
Datasheet descriptions say every SWx is a switching node output. Current symbol has several SW pins marked as input or powerIn:
  • SW1 pin 50 is marked INPUT; expected output.
  • SW2 pins 35/36 include powerIn and INPUT; expected output.
  • SW5 pin 45 is marked powerIn; expected output.
  • SW7 pin 42 is marked INPUT; expected output.
  • SW4/SW6/SW8/SW9/SW10/SW3 are generally marked output.
3. VCC buck supply pins should be power inputs
Datasheet descriptions say VCCx pins are power supplies for the corresponding buck converters. Current symbol has some marked output or powerIn rather than consistently power input:
  • VCC8 pin 7 is marked output; expected power input.
  • VCC2 pin 34 is marked output; expected power input.
  • VCC6 pin 28 is marked output; expected power input.
  • VCC1 pin 53 is marked output; expected power input.
  • Several others are marked INPUT or powerIn; normalize all VCCx pins to power input.
4. FB pins should be feedback inputs
FB1, FB2, FB5, FB6, and FB9 are external feedback-divider inputs per datasheet/reference schematic. Current symbol marks several as powerIn or output. They should be modeled as feedback inputs.
Conclusion
The RK806-1 symbol does not appear to have the suspected buck-output/VOUT physical pin-number mapping mismatch versus Rockchip/NanoPC. It should not block accurate RK3588 PMIC wiring due to swapped VOUT pins.
It does need symbol metadata cleanup before serious schematic integration: normalize VOUT/FB as feedback inputs, SW as switching outputs, VCC as power inputs, and LDO output/input directions according to the datasheet. Otherwise ERC and human interpretation can be wrong, especially because the PMIC buck output rail is actually taken from the inductor/output capacitor node connected to SW, while VOUTx is the sense/feedback pin, not the load output pin itself.
