Sweet. Thank you. I look forward to giving it a go.
Hello，you can download image from google drive now，
https://drive.google.com/file/d/1Ze_YGDT3B1-P57wPcm3gcVFcCMfBLspL/view?usp=sharing
a new quesion: now this image works well, but lsusb cannot display anything about my 4G miniPCIe card. lspci is the same: no information displayed. in other linux embedded system, lsusb works with this card.
so what should I do next? to make a new kernel with BSP? or some steps wrong? thanks
USB D+ and D- pin aren’t connected to mPCIe slot, so card detection fail if you use mPCIe form factor USB 3G/4G card.
Ok, Got it, thanks for your anwser 
Hello Guys,
my ap0 seems to be gone… No change to reload or bring it back, any idea ? Nothing worked, nether the steps from garywang, frank-w
Have you tried
echo 0 >/dev/wmtWifi
echo A >/dev/wmtWifi
?
Blockquote
more than 10 times, nothing seems to bring it back…
@Jackzeng Continuously testing this image. So far so good except the MMC booting process is locked in maintenance mode when the board is NOT properly shutdown. It forced us to use the root password, check the memory error check by manually and reboot the system. This is a crucial step, wont allow the hardware bring back until the mmc error check should be fixed by manually. Is there anyway we can make this step done automatically during the bootup time or skip this step?.
TIA.
I just use “ctrl+D” to ignore this problem when met it before, but maybe we could try to fix it in the next few days.
Hello，Can you post your logs here？I checked wifi and ap，it could be created.
@Jackzeng assume, BPI-R2 is a gateway/router product. It dont have display/keyboard. In such case it is not possible for the user to solve this issue.
if using SD-Card you can remove it, put it in external pc, read logs and check filesystem
if using emmc, booting bpi-r2 with SD-Card, and then read logs via ssh
not for every user…but network-admin should be able to do this 
you are right，I will try to fix this in next few days.
@frank-w，we could find a better and easy way to solve these problem，if R2 stuck in booting progress.
Hi，I succeed to create wifi/AP，and it works fine，could you show me your log？
my hostapd.conf
I use my PC connect R2 AP to post these messages to you：
Hi, good news… I will send you my logs in about 10 hours, when i arriving home.
I have the same issue, i do have the ap0 device but when i launch hostapd, the wifi SSID does not appears, I try with multiple devices.

Confirmed the issue was the entropy for WPA, as the system is doing nothing. I am still working to make all hardware.
