P89V51Rx2/P89LV51Rx2 / Re: P89LV51RD2 ISP Entry mode
January 23, 2008, 01:52:56 AM
I Know the command-line interface of FM,and I also write my own .bat file,and it workes well.But for mass production ,we don't use FM but parallel programmer.  We update to the latest version bootloader and change the default ISP entry mode only want to let the device execute use code immediatelly after every reset.So I must to try any other way.

Thanks

P89V51Rx2/P89LV51Rx2 / P89LV51RD2 ISP Entry mode
January 21, 2008, 11:20:33 PM
I am now use the latest version of bootloader for my RD2 device, and i want to specific a port pin to determine if the device execute the user's code or enter the autobaud sequence of ISP mode.But my P89LV51RD2 device have a old bootloader version which is V5,so i must to update my bootloader first,then use the "ISP Entry mode" command to set my GPIO pin,and then download my own code.My question as follow:
1, Can I change the default ISP entry mode by modity the HEX file of latest version bootloader?
2, Can I combine the bootloader and my own code to one HEX file and use one clik programming?

Sorry for my English,Thanks a lot.
