Something is wrong with either my Demo Circuit 890B or evaluation board, because PScope reports "no demoboard detected". I have tried many things, but now I suspect that I overwrote EEPROM stored values from my 2395A Demo Circuit, because I noticed that the WP/PROG jumper was set to PROG when shipped.
I've sniffed the I2C lines and see that the EEPROM is being periodically read, and these are the values I get:
5A 49 50 5A 49 0A 49 50 5A 49 0A 44 32 33 37 34 2C 44 43 32 33 39 35 41 2D 41 2C 59 47 47 38 30 31 54 2C 43 4D 4F 53 2C 2D 2D 2D 2D 2D 2D 2D 2D 0A FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF
in ascii, this looks like:
..or something close to that. (My board is the 2395A-A)
When the 890B board is reading with PScope attached, it just reads the first 6 values then stops and repeats, making me think that the the 6th byte in the EEPROM could be corrupted (0x0A), but I cant be sure.
