Hello Sir

I design new PCB for ST10F269, I use function Digital I/O analog I/O and RS232 transmit and receive the value .I use crystal 8MHz,But I don't use EXTERNAL RAM and EXTERNAL FLASH. And now I have a problem with the value into Hyper terminal incorrect ,I think The baud rate is not match, I'm check switch D15 D14 D13 for clock , It's not working. If somebody have a good idea for this please give one's opinion thank you

Hello sagai,

I suspect you have a start-up problem. Could you please tell me what is the hardware on RPD pon (pin 84)? A special hardware must be connected on this pin in order to ensure a good reset and a good sampling of port0 (clock etc...). More details are given in the application notes available on the following links: http://www.st.com/stonline/products/literature/an/8594.pdf http://www.st.com/stonline/products/literature/an/8906.pdf Hope this helps you, Please let me know if you have any question. Best regards, Najoua.

Hello sagai,

Yes of course you don't need external memories (RAM or Flash ) to get the ST10 to work. The external RAM on the FS FORTH board is used for debug purposes. The external Flash can be used if the user application size is greater than the internal Flash size. Regards, Najoua.

Hello Sagai,

Could you please tell me from where you are executing your application? I suppose from the Flash. If this is the case, I suppose that you are using the ST10Flasher tool to load the code in the Flash. Could you please tell me what are the steps done to load and to run your application? Is it possible to give me your code to have a look at it? Regards, Najoua.
