      the good news is that the 20230303 download has solved the pip3 install problem and i was able to install opencv as well. It is running on a usb stick at the moment. should this issue be closed?

      2)the format commands are not working as shown:

      ubuntu@coolpi:~$ lsblk
      NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
      sda 8:0 1 0B 0 disk
      sdb 8:16 1 0B 0 disk
      mmcblk0 179:0 0 58.2G 0 disk
      ├─mmcblk0p1 179:1 0 300M 0 part /boot/firmware
      └─mmcblk0p2 179:2 0 57.9G 0 part /
      mmcblk0boot0 179:32 0 4M 1 disk
      mmcblk0boot1 179:64 0 4M 1 disk
      zram0 254:0 0 0B 0 disk

      the tf chip is sda and sdb upon insertion via a usb adapter. the coolpi does not recognized the chip via the onboard tf card slot.

      ubuntu@coolpi:~$ sudo wipefs /dev/sda
      ubuntu@coolpi:~$ sudo wipefs /dev/sdb
      ubuntu@coolpi:~$ sudo wipefs -a -f /dev/sda
      ubuntu@coolpi:~$ sudo wipefs -a -f /dev/sdb
      ubuntu@coolpi:~$ lsblk
      NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
      sda 8:0 1 0B 0 disk
      sdb 8:16 1 0B 0 disk

      刷机两种方式都支持,主板的pwr按钮是系统开机、关机键。(注意电源适配器使用5V/2A及以上)

      @zhengbicheng said in 自动连接WIFI:

      @ccjjww1222 您误会我的意思了,我的意思是你可以用电脑利用转接器连接Cool-pi开发板的串口。使用串口输入账号密码后就是命令行了。

      他是想沿用树莓派预配置wifi信息,刷机自动连接wifi
