According to the server logs there is something unreliable with the link to the pic18.
Please check:
- the board power supply.
- the board quartz
- the serial connection.

If possible try another serial usb adapter and/or an another pc.

Check if pull-ups resistors are needed on RX & TX
or
Try another serial usb adapter or a MAX232 on a normal serial port.

There is too much spikes/glitches on the serial line.
And i don't understand the 23k256 clock !?!

Hello!
0. The server is not defined as a device.
1.PIC18F4620 flashed.
2. The LED does not blink.
3. On quartz 10 MHz.
4. If you turn off the quartz, the blinking of the LED appears at a frequency of 15 Hz.
What can be wrong?

Is the quartz oscillating properly ?

[ncbelov]

Yes.10.0005mhz

[Jeff]

Yes.10.0005mhz

Then check the SRAM connection/communication. An auto-test should be done at power up.

[ncbelov]

If the SRAM is not working, can there be problems with the LED blinking?

[Jeff]

If the SRAM is not working, can there be problems with the LED blinking?

blinking may be normal. Can you show me how it is blinking ?

[ncbelov]

No memory sram.
