Based on the schematic position -376, 175, the closest memory IC is U2 (16MB Flash) with part number W25Q128JVSIM. The connections for U2 are as follows:
  1. U2:VCC is connected to 3.3V.
  2. U2:GND is connected to GND.
  3. U2:~CS is connected to U1:QSPI_CSN (RP2040) through R2 (10kΩ resistor) and R11 (1kΩ resistor) in parallel for a combined resistance of approximately 909Ω.
  4. U2:CLK is connected to U1:QSPI_SCLK (RP2040).
  5. U2:DO is connected to U1:QSPI_SD1 (RP2040).
  6. U2:DI is connected to U1:QSPI_SD0 (RP2040).
  7. U2:~WP is connected to U1:QSPI_SD2 (RP2040).
  8. U2:~HOLD is connected to U1:QSPI_SD3 (RP2040).
The connections appear to be accurate for proper communication between the RP2040 microcontroller (U1) and the W25Q128JVSIM Flash memory IC (U2) using the Quad-SPI interface protocol.
