20706 PCM_OUT VOLTAGE IS HALF ,use A2DP_SINK sample test,please help check
Hello, everyone,
I have a problem with the CYW920706WCDEVAL development suite.The flash on the development board is MX25R4035F(capacity 4Mbit).You can download this program.When replaced with S25FL256S(cypress 256Mbi), cannot burn write.Here is the error message that reported the error.Similarly, I tried the recovery after appendix D, but the problem was still not solved.
| Power cycle the CYW920706WCDEVAL board and retry. |
| If this problem persists, the serial flash on the board may be corrupted. |
| Please see Appendix D in the Kit Guide for recovery instructions. |

Hi all,
I am having troubles trying to configure the CYW920706WCDEVAL dev kit as spi slave. On the Wiced Studio 6.2 SDK, I could not find any example that implements a spi slave.
So I have tried to use the code snippet and configuration that comes on the CYW920706WC DEVAL Hardware User Guide (Section 10.3). Unfortunately that configuration will not worked. I have also tried most of the configurations that comes within the SDK, on the spiffydriver.h (up to 87 possible configurations there).
I have throughly tested the following:
- SPI master device sends data correctly. Tested on scope (CS, CLK and MOSI). Also it works perfectly with a thrid party spi slave device.
- I have checked several times that the connections are correctly set as the recommended configuration (hw guide).
- The spi slave library init is correctly call on initialization. I can see the traces via UART.
- There are no other GPIOs used on the code.
I have attached the spi master files that I use on the project. Also on the application main code, the following functions are called:
spi_register_tx_rx_handler(nov_spi_slave_handle_tx_and_rx);
nov_spi_slave_register_data_received_cb(nov_spi_slave_data_received);
When the data is called the MOSI line is held high. The callback function is not reached at any point.
I have attached the spi_slave code that I have put together.
Any help will be most welcome. Please let me know if you need any other further info.
Thanks
Hello Cypress team
Please tell me following specifications of CYW20713.
1) REG_EN pin
Is there AC specification that REG_EN pin should be low-level at least before asserting it?
(In the other words, how long time should REG_EN pin fix low-level at least before asserting it? )
2)VBAT pin
Please tell me allowed maximum overshoot/undershoot voltage for VBAT pin.
Thanks,
Yoshinori Takano
Show LessHi,
I'm using the CYW920735 EVB-01. I've altered the DIP switches for SW9 to off position so that I can use the DEBUG header J13. Using Jlink command line I can connect to the USB Jlink device as this correctly reports the ID, but I can't connect to the CYW20735 via SWDIO and SWDCK as a plain vanilla Cortex M4? I've reset the board in case any firmware I've tried disables the P2/P3 pins and I have tried the SW9 DIPS in the on position. Nothing works! The CYW20735 definitely includes a debug interface so what am I missing? Is the only way to program the device via BT_UART? Please help!
Show LessHi
Customer is requesting that the output of Tx_Power on MBT is +12dBm.
Currently the Tx_Power is +3dBm.
I think that changing the +3dBm->+12dBm on the MBT source code,
this will satisfy the customer's needs, is it correct?

Why test console examples are not implemented?
Show LessHi
Customer is confirming Mode 1 ~ 9 described in Mode of Operation on page 9.
From Lab file [1752099R-RF-MIC(BT 3.0)-EZ-BT Module-CYBT-343026-01;CYBT-343029-01;CYBT-143038-01-V1.0.pdf]
Could you tell me what kind of settings are output for these modes?
Would you be able to contact us ASAP?
Thanks

Hi,
I follow the content of "CYW920719Q40EVB-01 Evaluation Board User Guide.pdf" on page 17 to "Make Target" of "demo.hello_sensor-CYW920719Q40EVB_01 download". It's fail even I used the combination of the "Recovery" and "Reset" buttons on board. My computer is HP Pavilion 590-P0086 desktop computer runninh Windows 10.
Please refer to the screen capture of the image attached, it's shown the COM port detection, the TeraTerm display and the message of the Wiced screens. The other image is the jumper setting of the hardware, as the original setting from you and matched with the jumper requirement from your document.
If possible, please give some comment if I could send some command to HCI to verify the unit. By the way, the echo message on the TeraTerm screen is during the regular boot up. If using the "Recovery"/"Reset" buttons, that screen is no any information popped up.
Regards,
Tony
