Hi,

I have an additional question related to the below question.

Re: Recovery after ota update failure CYW43438 / STM32F412

Besides manually selecting the FR app by pressing of buttons, is the following sequence correct?

1. OTA(not OTA2) update on a device is initiated.

2. The distribution of power to the device, for some reason, is cut off in the middle of OTA update.

3. The main application in the internal flash is corrupted.

4. The distribution of power to the device is restored.

5. The device boots up and tries to run main application in the internal flash but it's corrupted so instead it tries to run FR app in the external flash.

i' make just target like below

(1)  "demo.airplay_posix-BCM94343WWCD1-NuttX-NuttX_NS"

--> i got a error like below

WICED/RTOS/NuttX/WWD/WWD.mk:43: *** No NuttX low_level_init function for architecture ARM_CM4.  Stop.

make: *** No rule to make target 'build/demo.airplay_posix-BCM94343WWCD1-NuttX-NuttX_NS/config.mk', needed by 'main_app'.  Stop.

but when i make that same target for board "BCM943909WCD1_3" then it's working well.

(Note : i added "BCM94343WWCD1" board as a Valid paltform in airplay_posix.mk)

Now, when i check "nuttx.org" website then it shows that supported platform

==> ARM Cortex-M4 (with/without floating point unit: ST Micro STM32 F3/F4/L4/L4+)..

so, finally.. i think that it's a issue of wiced then it's not supported that Host controllers or platform..

i hope that have you some solution about it.

Thank you

Hi,

Just a question, what happens if ota (not ota2) is accidentally interrupted due to low battery?  Does the system reboot with the old(current) main program?

BTW, I don't have the actual EVB with CYW43438 / STM32F412 + external Flash.

Hello All:

I have an unusual ask - I want to use the serial flash memory on the Quicksilver_EVL for storing a LARGE amount of application data. The reason is this: in an ultra low power application where every uA matters, we want to be sending data over WiFi very infrequently, but I cant just declare a huge array. We are using the Quicksilver board which comes with many megabytes beyond the application space that can be used like an EEPROM or the like. Basically I want to use the sflash to buffer megabytes of sensor data so we can do one or two large data dumps per battery charge.

I've seen examples of defining user variables in the app dct - can I declare something that large? Ideally a queue would be nice, but if needed I suppose I could use a large array. I'm concerned about the latency of reading and writing to the dct as well - is there any way that can be reduced by using the sflash in a more "raw" format, ie reading and writing to raw memory locations from the application?

Any thoughts or suggestions would be very helpful. Thanks!

我在18年6月份下载的WICED6.2.1.2中把bt_dualmode_server例程合并到ble_bt_wifi_introducer例程，以实现WIFI+BT&BLE，测试过程中WIFI(STA模式)一直无法连接路由器。但是BT&BLE可以使用。

今天下载18年8月份更新的WICED6.2.1.2后,WIFI可以连接到路由器。但是BT&BLE部分无法完成初始化，log如图所示：

源码已经放入附件，请帮忙协助分析下原因！

谢谢！

Does it exist Windows 10 drivers for the CYW954907AEVAL1F kit so it can be use as a under windows as a WIFI Station ?

If yes what WICED application  needs to be download in the device ?

Hello,

My WICED Expansion for STM (STERLING-LWBTM STM EXPANSION BOARD) doesn't display the JTAG COM port, it only displays the USB -> Serial COM port. I tried reinstalling the driver but it still not working.

The board has the FT2232H chip from FTDI. I checked several discussions about this issue but all of them are old and lack of attachments. Below is my COM port display.

Can any one help me fixing this issue? As far as I know, this issue requires re-programming the FT2232H.

Thank you and best regards,

question asked to me,  does the cyw94343wwcd1 have a bridge power rectifier plug for 12 volts into the board. if so what port.

if more information or clarification is required, i can get it. thanks

I am using the PSoc6 Wifi-BT Pioneer Kit with the TFT Display Shield CY8CKIT-028-TF.

I have read CE223726 - PSoC6 TFT Display Interface with EmWin Graphics Library.

Is there a similar document to show how to use EmWin graphics library with Wiced instead of creator?

thank you in advanceE
