I don't understand. Do you mean that you don't have the sram memory ? This one is needed !

Re: HELP! SecSerialBridge software - ends with an error.
I have 1pc 23k256, the same with it. Can there be problems with a faulty memory?

Please check if the SRAM Clock is toggling.

How to check 23k256i memory?
Re: HELP! SecSerialBridge software - ends with an error.
Then check if the SRAM SCLK pin is toggling at power up.

OK.

It can be more specific. What is wrong with 2 drawing. PIC18F defective?
Re: HELP! SecSerialBridge software - ends with an error.
No. The lines are floating : Something is probably not connected (bad solder ?).

Re: HELP! SecSerialBridge software - ends with an error.
100mV is definitively too low. And the pin5 and pin6 seems to be inverted ?
Can you show me the pin 1 behavior from the power up during ~2 seconds ?
Re: HELP! SecSerialBridge software - ends with an error.
100mV is very small. 5 and 6 pins are not mixed up.
1 time I managed to download the firmware up to 34%. I had to reset the freeze process.
Now the device is not detected on the server.
