Hi there, I have an evaluation board of a HC11E9 and it has 512bytes of ram & eeprom. However this board has a buffalo monitor program burnt in it. And I writing some code that doesn't fit into the ram as the evaluation board only allows a user program address space from $0000 to $0046 and $0100 to $01FF. Is there any way that i can access more memory either by adding external ram or by reconfiguring the EVBU board as I greatly need to test my code which is about 800bytes. And i don't wish to remove this buffalo monitor.thks Chamy cheers! _________________________________________________________________ Join the world’s largest e-mail service with MSN Hotmail. http://www.hotmail.com

I think that you also have from $B600 to $B7FF in EEPROM available to you. When you are loading into EEPROM you will have to drop the Baud rate to 300. To do this: At the BUFFALO prompt type mm 102B <return> it will reply with 102b 30 type in 35 <return> Then change the Baud rate on your terminal program to 300 and download your program in the usual way. At the "DONE" prompt, press your reset button and reset your terminal to 9600. If you have any problems e-mail me.

Most EVBUs came with some extra processor chips: either windowed EPROM or OTP. These have 4K of memory below BUFFALO. If you don't still have the extra chips, the OTP is 68HC711E9 and can probably be obtained from an electronics supplier. I have always had to use PCBug11 to program the EPROM or OTP.

Hi there, I have tried the suggestion given by Mr Trevor. Apparently, BUFFALO doesn't allow me to change the BAUD register.I have tried using the MM command on PORTA to verify that the MM command is working and it does. When I tried MM 102b and it replies with <102b 30> then I typed in 35 and it just hangs. Any keybaord input from me doesn't get echoed on to the terminal. then i tried MM 102b and inputting 30 just to see if the buffalo responded the same way and it responded well and showing the prompt. then i tried MM 102b again and inputing 31 but this time any input from the keyboard, garbage is displayed on the terminal, then i reset the board and type MM 102b it shows 30 is in the BAUD register. Is there any jumpers that i have to change. I have tried this on another EVBU board and i get the same scenario.Pls advise. Thks alot!

Hi Once you have changed the baud rate on your evb you must then immediately change the baud rate on your terminal program. Otherwise the board is set to 300baud while your terminal is still at 9600baud Regards Trevor -----Original Message----- From: Chamkaur Singh [mailto:] Sent: Friday, September 13, 2002 11:08 AM To: Cc: Subject: RE: [m68HC11] EVBU HC11E9 Memory Hi there, I have tried the suggestion given by Mr Trevor.

> You MUST change the speed in your terminal program also to match > your board's new speed. You could leave the Baud rate alone and see if your terminal program has a line pacing option, I use the original WIN3.1 terminal program for BUFFALO and find downloading to the EEPROM works fine if you set the line pacing to 1/10 sec per line. This way you don't have to mess with the Baud rate.

I use that one too, but Hyperteminal has a finer step down to 1 mS timing between characters. I use Hyperterm with my download program that can program either internal EEPROM or serial EEPROM connected to the SPI. It work very well. It's a pity that it doesn't have the nice function keys that the old WIN3.11 terminal has, which I find indispensable..
