#46576 - RE: code into eXternal RAM Responding to: ???'s previous message |
Hi Pranav,
Things are clear now. But one more question appeared. Again piece from BOOTSTRP.ASM: ; .... ; Program execution may then be started by telling the bootstrap program the ; correct starting address. The format for this is to send a slash ("/") ; followed by the address in ASCII hexadecimal, followed by a carriage ; return. Example: "/8A31<CR>" So doesnt that mean, that i wont start my system from XRAM wihout PC (sending XRAM program start address)? I mean, lets say i load in XRAM code with the vector table from 1003h,... and program starts from 1033h. I turn OFF the system. SET EA=0. Then turn the system ON. How to let XRAM know to start program from 1033h, because ORG 0 is reserved by BOOTSTRAP(?) If i will leave EA=1 before powering up system, it will go to bootstrap loader. I dont need that. Doesnt it finally mean, that i'm stucked, or just dont know something. Rob |
