Problems connecting to STEVAL-WPC86TX with STSW-WPSTUDIO

[sjones]

Following on from 

Solved: Cannot connect STWBC86 to WPSTUDIO V1.8.4 - STMicroelectronics Community

I am still getting the "Unable to find an [TX]WBC86 device"' message when' I try to connect.

Originally the log file just showed the 'Failure to load DLL' message

I  installed all the Visual C++ redistributable versions (2005/2008/2010/2012/2013/2015, x86 and x64) as suggested

The log file now shows read/write errors when trying to contact the board
I made a capture of the I2C bus on the board which is below, followed by the WPSTUDIO (v 2.2.5)  log file

Just a couple more things...

I have jumpers on the SDA, SCL and INT headers of P2

The board has LEDs D6 (power) and D5 (I2C initialised) illuminated.
On power up, or pressing the S1 reset switch I get the following on the I2C bus:

[willzhou]

Hi
The log show I2C read is NAK and data is invalid 0xFF.
Seems ft260 dongle have some issues.
I suggest you change ft260 dongle
https://www.st.com/en/evaluation-tools/steval-usbi2cft.html

or other i2c devices, like STM32 MCU refer to this like
https://github.com/STwirelesscharger/STWBC86_NUCLEO_L476RG

Hi,

  I did some more testing. 

  I isolated the STM TX chip from the FT260 chip by removing the jumpers on P2.
  I connected a bus pirate board to the I2C SDA/SCLK/GND (and set the 5V pull up on the bus pirate)
  I then used the bus pirate to generate  I2C traffic to the TX chip.

  The TX chip still ACKed the write requests, but NACKed read requests, exactly the same as seen in the recording below where the FT260 chip was generating the I2C traffic.
  When bus pirate scanned the address space for devices it found 0xc2 (0x61 write) but not the expected 0xc3 (0x61 read).
  This indicates that the problem is with the TX chip, not the FT260 chip, and buying an FT260 dongle will not fix the problem.

  It looks like the board is broken.

Hi

also please use attach debug tool to check ft260 connect logs, it is build by python, runing need some time, correct log is like below:

I have the same issue with the board (WBC86TX). The FT260 Debug Tool gives the following Output:

According to my Logic Analyzer, the Board seems ACK "ADDR+W" but NAK "ADDR+R". So is there any state
possible in which the chip does not respond to a read request?

[willzhou · Accepted solution]

Hi

Seem your board have some issues, please try "wlc_ft260_Recovery.7z" at this link

Wireless Charging solution Wiki - STMicroelectronics Community

[MaSiBe]

I tried the recovery tool, but this gave me:

Is there anything else I can try, or should I get a new board?

[willzhou]

Hi

Do you try many time and get same results "read chipid 0xFF version 255"

If yes, this mean can not read chipid and chip is broken, suggest you change chip or boards.
