M88, M168 work flawlessly but M328 fails during verification. I've also got the MyMultiProg add-on board, which allows me to program the chips without the need of a target circuit:īut no difference. In all three cases, power supply is rock solid 5V, checked with my oscilloscope during programming as well. The M168 still works flawlessly with the MySmartUSB, and an M88 also works in my target board.
SPEED TECHNOLOGY CO AVRISP DRIVER UPGRADE
support replied to my question that my setup should support the M328, "since it is only a memory upgrade compared to the M168". When I read back the code from the chip, I find that some code is written, mostly in the very last part of the memory. hex-file, it keeps returning a checksum verification error after programming. The programmer will find the chip, but when I try to burn the. I'm using a MySmartUSB MKII programmer with the latest MyAVR ProgTool (v1.39). I've swapped the AVR with a brand new M328, but my programmer refuses to write the. All works well, but I would need some more codespace to implement SD/MMC support. I'm building a 6-channel voltage logger, currently with an ATMEGA168.
It's been a while since I've done some projects with an AVR, but now I've started one again.
