wena chip ekak aluthen bootable karala try kara da?
sd card slot eka replace karana eka nam loku case ekak nemei.

BTW I read about your issue. It looks like this is a common software problem.
there are some configurations to skip sd card boot, and some say this happened after a usb boot. this can be reverted
Also you can try to update EEPROM

since you can read the sdcard after boot, this is unlikely to be a hardware problem

//there are some configurations to skip sd card boot,// If you have them handy, can you share those links?

Bro! Thanks a lot. Your comment triggered another path in my mind to update the EPROM. I update the EEPROM from the terminal. That works well, mate. Thanks a lot. Now it is working.
