By default, CYBT-343026 is shipped with Ez-serial FW (https://www.cypress.com/documentation/software-and-drivers/ez-serial-ez-ble-module-firmware-platform ).
Here are some KBAs to start with eval board:
thank you for the information.
When I connect the CYBT-343026-EVAL board it does not behave as described in the "EZ-Serial WICED Firmware Platform User Guide for CYW2070x-based Modules.pdf" Doc. No.: 002-25029 chap 2.2 Factory default Behavior page 9.
The board does not send out the boot event as described. Same behavior on 2 boards.
2 comports shows up on my PC, and I have been listening on both.
Can you check all the settings are correct as given in pdf?
You have to check the boot messages on PUART (usually higher number COM port), not on both the COM ports.
yes, I am listening on PUART with the setting from page 9 bauderate 115200, 8 data bits no parity and 1 stop.
checked the other UART (the lower) just to be sure. No response.
Checked with oscilloscope on the XRES pin of CYBT343026 pin 3 that it is following the reset key - ok.
Checked all other pins of the module.
On pin 6 there is a 100ms "message"
Pin 6 is not connected on the evaluation board.
This should not be the behavior of the board.
Can you try recovering the board? Putting 2073x, 2070x, and 20719 Based Devices or Modules in HCI Mode – KBA225450
And then programming with some non BLE app, say GPIO and see if it is working.
I agree with you - this should not be the normal behavior - I have 2 boards with this behavior.
A sticker on the backside of the boards says
the SPI2_MOSI pin is allready low, so maybe the module is allready in HCI mode.
where do I find the GPIO app and what program do I use to load/program the module ?
basically I'm going to use EZ-serial functions of the module to exchange data with mobile telephone android apps and windows 10 PC apps.
So I would like to load the "ezserial_343026-CYBT_343026_EVAL-rom-ram-Wiced-release.hex" to the module, to have it behaiv like described in the "EZ-Serial WICED Firmware Platform User Guide for CYW2070x-based Modules.pdf"
This must be possible with the platform and procedure in your last message ?
Yes, the procedure is same as I mentioned in my previous response.
I managed to update the CYBT-343026 with the ezserial_343026-CYBT_343026_EVAL-rom-ram-Wiced-release.hex with this commandline in a .bat file
ChipLoad.exe -BLUETOOLMODE -REBAUDRATE 115200 -LAUNCHADDRESS 0x00000000 -PORT COM5 -BAUDRATE AUTO -MINIDRIVER uart.hex -FIRMWARE ezserial_343026-CYBT_343026_EVAL-rom-ram-Wiced-release.hex -BTP CYBT_343026_EVAL_SFLASH.btp
Now I got the right response from the module/eval board on the highest serial port no:
May I suggest that you add the above commandline to the firmware file CYBT-343026-01 WICED EZ-Serial FW Image V1.1.14 (.hex, .cgs).zip or the KBA223428 document
All files need to be in the same directory:
