1. You should state as much information here as possible for people here to help you. Don't expect them to guess what you intended to do.
2. If you are talking about http://www.embeddedlogic.com/embarchiv.../boot3.asm , there is enough guidance within this file: - you should have a program memory starting from 0 prgrammed by boot3.hex, either internal or external (and EA set accordingly); - you should have 12MHz xtal - you should set 2400 Baud (8 data bit, no parity, 1 stop bit) and no handshake! - upon reset, the terminal should receive the following message: Steve's 8051 bootloader - 18 April 1995 Download Intel hex files to address 8000h In the following, it is assumed that you send an intelhex file, which is loaded into RAM at position 8000h; if end-of-file character is sent (1ah), it jumps into 8000h. That's all. Have fun! Jan Waclawek |
