Dear Sir,
Thank for the reply. I intentionally pressed the keyboard to stop the loop process to get print out/screen dump. If i didnt press the key it would continue eternally. I later installed latest manjaro Gnome to find that it boots but wifi does not work and when wifi does not connect or turn on. The program freezes if not used for more than a minute and when connceting to HDMI the mouse and keyboard doesnt work after a minute.
Just 1/2 hour ago i downloaded https://github.com/radxa/radxa-zero-images-released/releases/download/radxa-zero-v20211028/zero_debian_buster_xfce4_arm64_20211028_1030-mbr.img.gz
unpacked with peazip7 . Used win32_diskimager 1.0 software to write the image file on the 32GB SD card. connected my usbserial dongle to the RADXA 512mb non EMCC board on one end and the other to my windows laptop. Opened Terraterm with baud selected to 115200. On powering up the board I found the board boots up with out any issue. . With instructions from web page https://wiki.radxa.com/Zero/Debian sucessfully connected to wifihotspot on my mobile telephone. I didnt upgrade as I was afraid of failure. I instaled python , PIP, numpy etc successfully. Also downloaded the bluetooth package and got bluetooth working. The web address from where i downloaded the image is https://github.com/radxa/radxa-zero-images-released/releases . Please find below the entire screen dump of the serial console if it might be useful to any novice like me in future. I will update here any issues after connecting via HDMI as i dont have the HDMI screen at present. All this what is discribed above was through serial console.
