I've made a custom board with an AT90CAN128, and I can't get my USBTinyISP to connect to it. I've verified the programmer is good, as it connects to a 328p and a AT90CAN128 on a dev board fine.
I made a second board now with a spare IC, and only soldered the IC, an ICSP connector, and a 10k pullup resistor for RESET. I can not get that one to connect either. My board does have a 16MHz crystal, while the second board does not.
I can find no solder bridges or mistakes so far on my board. I bought this exact IC from Digi-Key. I thought all Atmel AVRs were shipped with ICSP fuses enabled. Am I missing something, or am I going to need a high voltage programmer?
Current consumption is 40mA, that includes the power LED, a 3v3 regulator, and a MCP2561.
