I am using WICED SDK 6.1 with FreeRTOS and LwIP.

I am trying to test OTA updates on my CYW43907 based module with custom code receiving the image through secured MQTT. The first ~140KB of the image is received and processed but then all network activity stops. I cannot send or receive and I cannot reach the device through ping from a computer. I think something has died in LwIP, or something in the WICED network layer has stopped pulling packets from LwIP.

I enabeled the LwIP stat print out and I think there is an issue with the PBUF_POOL_RX buffer.

MEM PBUF_POOL_RX

avail: 45

used: 45

max: 45

err: 866

The full LwIP stat output is attached.

Any ideas on how to troubleshoot this?

I enabled debug and error prints in WICED and I am not seeing any errors or anything that stands out regarding the TLS or Network modules.

hi Sir,

Are there any document describes the power saving with CYW54907?

I only find some documents with CYW43907.

thank you.

Hi

The customer would like to make Ethernet to Wi-Fi converter by CYW43907.

In such case, CYW43907 will receive Ethernet frame via MII interface and transfer it as Wi-Fi as follows.

(Not to use L3 layer or higher in this case.)

Host CPU =MII=> CYW43907 =Wi-FI=> AP

In order to do that, we need to control MAC layer by WICED API but I can not find it in the documents.

Q1: Is it possible to configure it by WICED API?

Q2: If yes, could you tell me which API we should use to control MAC?

Q3: Ideally, is there any sample source code for such application?

Thank you.

I am using WICED-Studio-6.0 on CYW943907AEVAL1F platform.

I can't make both OTA and OTA2 work for CYW43907 now.

Please give your comments and advise to shoot this problems.

For OTA2, I tried the following procedures;

I can't succeed step 6. I couldn't make it

"After download, reboot the target by "update_reboot" to extract the new firmware.

After extract, reboot the target again to start new firmware running. "

For OTA, I tried the following procedures;

When I tried "Perform factory reset on the WICED evaluation board" but I couldn't succeed.

Seems to me, software updated was done but can't make factory reset.
