QCA7005 SPI response error #144

Closed 1tianmaxingkong1 closed 2 years ago

1tianmaxingkong1 commented 3 years ago

When using the Raspberry Pi to check the status of QCA7000 for the first time, QCA7000 returned an error status of 0x5A. The access and response messages are as follows: MOSI: 0xDA 0x00 0x00 0x00 0xDA 0x00 0x00 0x00 MISO: 0x00 0x00 0x00 0x00 0x5A 0xD6 0xD6 0xD6

Does anyone encounter similar questions? What does 0x5A mean and is there a solution?

We have seen similar things when connecting the SPI directly. What helped was to put 10 Ohm series resistors in each SPI line. MISO, MOSI, CS and CLK
