(...) Well, if the power LED didn't light, then you don't have power to the MAX232 chip (unless the LED is installed backward or broken). It sounds like you've already skipped ahead without passing the first set of tests, which I've copied from the (...) (27 years ago, 19-Jul-97, to lugnet.robotics.handyboard)

Hi, I've encountered some problems assembling the interface/charger board. After installing the 16-pin socket for U16 and the capacitors and then mounting the MAX232 chip, I then applied power to the board. But, the PWR LED did not lit up and the (...)

For those of you who haven't heard, Motorola is currently offering a deal on the ColdFire Evaluation board. The board comes with 4Mbytes of DRAM (in the form of a 1Mx32 SIMM) and 256KB of Flash ROM (two 128KB Flash ROMS), two serial ports, a (...) (27 years ago, 15-Jul-97, to lugnet.robotics.handyboard)

I'm currently assemblying a handyboard and came across some literature for Motorola's 68HC12 microcontroller. The one thing that attracted me to it is its built in memory-mapping capabilities.

James, Thanks for following up. The reason for this behavior should be fairly evident -- there are traces very close to the mounting screw holes. Your metal washers must have shorted them together, affecting wires to the memory. I do mention to use (...) (27 years ago, 11-Jul-97, to lugnet.robotics.handyboard)

| | RE: Corrupted or Invalid Pcode?
|

I've discovered the problem. When I mounted the Handyboard, I used metal standoffs. When the board is mounted, it doesn't work. When it isn't, it does. The solution then I guess is to use nylon washers to isolate the Handyboard from the standoffs. (...) (27 years ago, 11-Jul-97, to lugnet.robotics.handyboard)
