Hi, I am programming ATMEGA2561 with 250KB code size.
Programming time matters and code updates are frequent.
Therefore I have benchmarked programming times just to discover suprisingly long programming time with JTAGICE MKII in ISP Mode. Here are my results:
11.6s AVRSTUDIO4 AVRISP MKII
16.3s AVRSTUDIO6 AVRISP MKII
18.5s AVRSTUDIO4 JTAGICE MKII JTAG mode
23.5s AVRSTUDIO6 JTAGICE MKII JTAG mode
61.8s AVRSTUDIO4 JTAGICE MKII ISP mode
61.6s AVRSTUDIO6 JTAGICE MKII ISP mode
Measured between clicking 'program' and observing message 'programming OK', using AVRSTUDIO6. Programming FLASH only, preserving eeprom, no verification, erasing entire flash before programming.
I am using external reset option with JTAGICE.
The other connector was disconnected when changing between ISP/JTAG modes.
Because the target is using 14.5MHz oddclock, I have used 2MHz programming frequency in all cases.
1. Is this JTAGICE MKII programming time in ISP mode consistent with you results?
2. Is JTAGICE MKII slower than AVRISP MKII in most cases even in JTAG mode?
3. What is real-life situation with AVRONE?
