I met with Actions yesterday, and reflect the problem from reviewers and developers like you.
1. The SoC temperature should improve again. I have send your test and summary to them.
2. We have patched the Ethernet drivers, the speed has been improved again to about 8MB/s. We will release it in next version.
3. We may could find a solution about how to burn the system into emmc from SD card.
4. We hope some early reviewers can reflect more and more inssues for us, that we can test, reproduce and know what you are care, so that we know how we can improve and satisfy users requirment.
