So what is different?

Post by bluejets »

Used the little black usbttl adaptor for yonks to program the prominis with no problem, still works on my old stock items.

Bought a new batch the other day and problems programming, just would not load up.

Re-loaded the bootloader but no luck there either.

Finally problems disappeared by using a clone FT232 unit.

Might be helpful to some if this comes up in future.

Edit:- Most likely a dodgy driver..

Just played with the system again and noticed a code 10 in the driver for my old faithful ...... :roll: :roll:

What chip on the USB uart?

CH340, CP2102, CP2104, PL2303 ...?

There is much crap around ....

The left one ist stamped FTDI, but reports as a PL2303 and the one on the right has the label on the chip removed,
is a CP2102, but works only erratic.

And with your 'clone FT232', I would be careful. The original FTDI is programmable an can be checked and programmed with a tool from FTDI.

Maybe you give it a try with your 'clone FT232', ;)

No worries, I'll stick with the FT232BL (red unit) as I had to install FT drivers to get it to work and it works repeatedly without a fail.
Tried it around 20 times now.
