Problem: When burning a new chip, I get a "device did not program" error.
I'm using the following hardware:
- Pocket Programmer II
- UV Eraser
- 27C512 chip (MaxEffort ME-R)
The process I’m following is:
1. Erase the chip with the UV eraser.
2. Start the Pocket Programmer software, and then insert the chip into the programmer.
3. Verify that the device is erased and get a “device erased” message.
4. Select the chip type (27C512).
5. Load the buffer.
6. Select Program Device, and this is where the problem lies. It appears the first half works ok, but then it looks like it is verifying the burn and that’s where I get the “device did not program" error.
What am I doing wrong?
I've tried this with several chips and continue to have this problem. Is the process I’m following wrong? Is there a step I’ve missed?
Thanks,
