Hello mates,
I have been trieng to read this mcu (oj66d)with upa, no succes.
(By the way i read it like hc908)
i also tried with TU also no succes, i placed xtra cable on pin 25, still no help.
Upa should be able to read this mcu but it keeps failing.
Does someone know if i should lift some pins.
Best regards Honingkoning.

And also Reset / IRQ pins, and hit the auto baud rate button, it should find the connection speed.

Thanks guys after lifting the 3 mentioned pins and hitting baudrate it was succesfull.
By the way what does the baudrate mean or do, because i lifted the pins but upa still not read the mcu, after hitting baudrate it was ok and the same with writting mcu i had to hit baudrate first other wise no programming able.
Thanks Honingkoning.

Baud means speed, is different for every crystal value. For example, if crystal is 8MHz, the baud is 14401.

You must only lift IRQ pin and give power on pin 26.
