A [[Metaboard]]-based programmer. | A [[Metaboard]]-based programmer. | ||
This programmer behaves exactly like the USBasp stripboard programmer. | |||
In the current incarnation, this programmer is not as stable as the USBasp version. | |||
We need to figure this out, e.g. ask [[User:cs|Christian]] for advice. | |||
Symptoms are aborted operation during read or write. Usually it helps to try again and to run verify as a separate step. | |||
avrdude: error: wrong reading bytes b8 | |||
Note: This programmer has a bootloader on it, so it can be updated over USB. There is a jumper to enable the bootloader. This jumper must be '''off''' when using it as a programmer and '''on''' when accessing the bootloader. | |||

Sometimes, the following happens: | |||
<tt> | |||
avrdude: erasing chip<br/> | |||
avrdude: error: programm enable: target doesn't answer. 1 | |||
</tt> | |||
This has shown to be caused by wrong crystal fuse settings, typically an issue when programming fresh chips. | |||
To fix, program all fuses first, before erasing the chip. | |||
