jyetech scope - all finished: back side

UPDATE:

I received a free replacement DIY KIT from jyetech.com which works much better. The old one just doesn't run with new firmwares properly. I suspect a flawed cpu, so I'll replace the chip some day.

Check the seeedstudio.com / arduino.cc forum for support threads.


WARNING:

I managed to brick the scope by updating to the latest firmware ( 113-06201-080 [2009.07.06] ) !

Reflashing -070 DID NOT help at all.

If you should try this, make a backup of the current firmware / eeprom in the chip before flashing anything new! The scope saves data to the eeprom that affects its operation (screen menu / timebase). The eeprom is not erased during chip erase, as a fuse bit is set to keep the data. The 10pin header IS NOT isp compatible, you need to make an adapter. The bootloader lock bits are NOT SET, so flashing will kill the bootloader!

According to the PDF manual, one needs this to fully program the device:

a) firmware.hex
b) bootloader.hex
c) eeprom.hex

Right now only the firmware.hex is available, b) and c) are nowhere to be found.

DO NOT FLASH your device !

Please note that a new hardware version of this device has been released, therefore these images will most likely not apply to it.
