We design an IoT module using PSoC6(CY8C624ABZI-S2D44) and a Wi-Fi module(Murata Type1LV, which uses CYW43012).
Our board schematic and pin configuration are the same as the Cypress development kit(CY8CKIT-062S2-43012).
Environment
------------------
* ModusToolbox v2.2(same behavior with v2.3).
* Board
+ CY8CKIT-062S2-43012(works good)
+ Our board(same schematic and pin assign as CY8CKIT) -> has the issue as below
* Lot Number of Type1LV
+ SS9123002(on CY8CKIT)
+ SS0N18005(on our board)
Steps to reproduce the issue
---------------------------------------
* Create a project using `project-creator.exe` from `AnyCloud_MQTT_Client`.
* Set WiFi info(SSID and password) and MQTT broker info(IP etc.).
* Build, program, and run for each board(CY8CKIT and our board).
Behavior
------------
* On CY8CKIT
+ works good.
+ Capture_GOOD.PNG(the first image)
* On our board
+ Wi-Fi module initialize error on waiting F2 function.
+ This loop timeout. https://github.com/cypresssemiconductorco/wifi-host-driver/blob/19968e1b77db296b1be9f1352147f6152003...
+ Error in the line 475 is printed.
+ Please see the attached Capture_BAD.PNG(the second image)
- Some additional printf() message are added.
- The highlighted line is the error from the line 475 of WiFi_Host_Driver/src/bus_protocols/whd_bus_sdio_protocol.c
+ line 468 `whd_bus_read_register_value()` return 0 and `byte_data` value is always 8.
- on CY8CKIT, `byte_data` changes to 6 after about 100 cycles.
Questions
-------------
* What is the possible cause which makes this difference?
+ I guess that `whd_bus_read_register_value()` reads the register value of the SDIO target(CYW43102).
+ Why the response is different between CY8CKIT and our board?
* How to solve this issue on our board(schematic or firmware)?
