4) On my revision of the PCB, the DC-DC converter is too close to the ISP pins to allow for the IDC connector’s key; like Ed Hubbell, I had to shave off the IDC connector key to get it to fit to the pins. I see that later PCB revisions have moved the DC-DC converter to the right, and still other revisions have rotated the ISP pins 90°. For this reason, perhaps multiple Guides for firmware updating (or branches to the existing/monolithic Guide) should be considered.
As of this writing, the Assets for 8.2.0 and 7.1.6 do not contain “flash.bat” nor “eeprom_24.bin”.
2) The filename for firmware releases is now “openevse.hex”, not “open_evse.hex”.
3) The OpenEVSE ISP programmer that I was shipped in Oct2019, Order #6383, was a Polulu USB AVR Programmer v2.1, which shipped with a std. ribbon cable and IDC connector; therefore, the instruction in Step 4: (“The yellow wire on the 6 pin connector aligns with pin 1 of the ISP connector.”) is not applicable. Perhaps I was not sent a harness I was supposed to receive, or a previous programmer that OpenEVSE shipped had a different harness.
No edit, so . . . for accuracy, the ISP pins were moved left, not the DC-DC converter module moved right, but the issue remains the same.
