@ -110,6 +110,11 @@ Quartus will produce a .POF file. This can be converted to a .JED file for Atmel
### JED => SVF
An SVF file can be produced using [Microchip's ATMISP tool](https://www.microchip.com/design-centers/programmable-logic/spld-cpld/tools/software/atmisp), which is also Windows-only.
### Used chips from China
The chips can be pre-used if you bought your ATF1502AS from China. Sometimes JTAG interface is disabled on them, preventing normal JTAG operations.
To enable JTAG, connect +12V power through a 2.2kOhm resistor to pin 7 on the 68000 CPU connector. Afterwards flash the `atf1502as_erase.svf` file to the CLPD. Then you can follow the normal programming procedures.
## Thanks
- *lvd* for providing most of the above information and helping me come up with the Linux flashing procedure.
- *majinga* and *go0se* for testing and helping improve this procedure.
