EC25 QuecOpen toolchain issue

Hi all!
I assembled kernel 4.18.11 from sources and got adb shell to device.
All troubles below (i added kernel info and adb response to this listing):

syrf@quec:~/workspace/ec25/ql-ol-sdk$ uname -r
4.18.11-quectel
syrf@quec:~/workspace/ec25/ql-ol-sdk$ adb devices

Done.

Can the community tell me where I am going wrong?
Can Quectel representatives help me solve the problem in private messages, because our dealer does not have enough information?

Dear Denis,
Thanks for your inquiry in Quectel forum.
For your issue, it is better to ask in the Open Solution. Thanks!
