OTA not working

[rohitkpdj]

After transferring the code through  OTA  i am getting a confirmation msg (tranfer complete) in the android nxp iot tool .But after that the code is not getting flashed on the target board.I found that the code has over written the existing OTA CLIENT code,but it is not  showing any output.I have debug the code also and MCU reset function is also called,What might be the reason any idea to resolve this.

Hi,

What type of file that you are sending Over the Air?

What is the version of the IoT Toolbox that you are working on?

Could you please make a simple test? Could you please send the OTA Client example srec file over the air?

Regards,

Mario

Hi Rohit,

I ran by my side another test and it works.

I flash the bootloader.

"\SDK_SDK_2.2_QN908XCDK\tools\wireless\binaries\bootloader_otap_qn908xcdk.bin"

Then I flash the qn908xcdk_wireless_examples_bluetooth_otap_client_att_freertos and the same file I created the s19 file and srec file and for both sides, it works. Version 5.0.6

Regards,

Mario

Hi Mario,

I am trying with bare metal (bm) not Rtos, for that its not working, do we

need to change the flash to internal flash, or we need to initialise

external eprom, that is we need to change gEprom_type .

Hi Rohit,

I ran by my side and it works.

Please see my process below. What is the process that you are following?

1. I program the bootloader_otap for the QN9080.

2. I program the QN9080 qn908xcdk_wireless_examples_bluetooth_otap_client_att_bm example.

3. Select the s19 file that I created from the MCUxpresso.

4. Update the firmware

5. Transfer successfully

6. The new firmware starts the adv after I press the button.

Mario
