Above is the schematic for USB type.c power sink(UFP),dead battery mode,boot configuration is BP_NoWait, device configuration is Safe_Configuration.:
When X2 connect to type.c power sink,VBUS is 5V, LDO_3V3 is 3.3V,LDO_1V8 is 1.8V, VIN_3V3 is 0V
Issue: 1.device not load external confirguration from SPI, SPI_CLK, SPI_MOSI, SPI_MISO no signal. The device performance not act as boot configuration:BP_NoWait, then checked datasheet, for unused pin need and SPI_CS handle as below:
1)：GPIO1:Ground pin with a 1-Mohm resistor
2): I2C1_SCL: pull up to LDO_3V3 with 10-Kohm resistor
3): I2C1_SDA: pull up to LDO_3V3 with 10-Kohm resistor
4): I2C2_SCL: pull up to LDO_3V3 with 10-Kohm resistor
5): I2C1_SDA: pull up to LDO_3V3 with 10-Kohm resistor
6): SPI_CSZ: pull up to LDO_3V3 with 3.3-Kohm resistor
With all this, when power on,device not load external confirguration from SPI, SPI_CLK, SPI_MOSI, SPI_MISO no signal.
Question:i) If device should act as:when power on,device not load external confirguration from SPI, SPI_CLK, SPI_MOSI, SPI_MISO no signal?
ii）If not, what issues can you found from my design?
iiI) I also try to change to below mode(R8 UN-mount,change R17 to 8K2):
device performance still:when power on,device not load external confirguration from SPI, SPI_CLK, SPI_MOSI, SPI_MISO no signal.
Can you help me for: If device should act as this
