OTA-requestor-app issue on NXP i.MX8MM

[yinliangren]

I met the following problems when I was working on the project matter with NXP i.MX8MM board.

Current state

1.    I ran OTA-requestor-app on the YOCTO system to upgrade the thermostat-app.  44,384 packets were received and used for more than three hours.

2.   After I used gzip compression, I used OTA-requestor-app to upgrade   the thermostat-app  .16,319 packets. 36 minutes.

3 . The upgrade files received by the preceding two methods can run properly.

Present problems :

1.  How to solve the problem of long OTA upgrade time

2.  I changed the thermostat-app  software version number(/connectedhomeip/src/include/platform/CHIPDeviceConfig.h)

2.  I run the thermostat-app  at YOCTO.What Can I do if the OAT upgrade command fails to be executed?The information is as follows:

Execute a command:

sudo ./connectedhomeip/out/standalone/chip-tool  otasoftwareupdaterequestor announce-otaprovider 5678 0 0 0 8888  0

Hello,

Make sure you are using the CHIP thermostat example for the MX8MM, the matter examples will be upgraded but so far is the only examples it provides.
