Bluecore can't connect to CSRA64215

[kingmercian]

Hi @lorf , I am hoping you can tell me where I am going wrong!

Connections:

CSRA64215	Resistor	FTDI	BATT
GND			GND
3.3V			3.3V
SPI_EN	10KΩ		3.3V
SPI_MOSI 220KΩ		RI
SPI_CLK	220KΩ	RTS
SPI_CSB	220KΩ	DTR
SPI_MISO	220KΩ	DSR

I am using BlueSuite 2.6.x and my env is Windows 10, I am using the generic fake FTDI with pinout from eBay and I am using libusbK with your .dll replacing the one within BlueSuite.

BlueSuite detects the FTDI interface but when attempting to connect I get "Error detecting chip type (unable to start read (invalid control data))"

Any input would be appreciated.

After more digging:

So looks like it isn;t connecting to the FTDI even though it all looks good from device manager:

Also looks similar to this issue, as that user did I also use two PSUs (one to power FTDI and one for CSRA64215) and I had also tried connecting ground from FTDI to CSRA64215 but this causes the FTDIs LEDs to light up permanently and prevents it from connecting to the computer.

I think 220 KOhm in signal lines is too much. Please try 220 Ohm resistors.

[kingmercian]

My bad, I meant 220 Ohm.

For some reason it started working after unplugging and replugging the ft232 a few times.

Thank you.
