Dear fans, I built a single board of 8051 which is very standard with 8051, ROM (running MINMON), 64K RAM, 8255 X 2, RS232 port, etc. MINMON is placed in 32K ROM (starting address 0000H ) which has 32K shadow RAM. So, when program loaded. I disable the ROM and come to 64K RAM. It works fine. I had some ASM programs running fine. Now, I tried to use SDCC for my board but I have problem. I can compile successfully sdcc, sdcdb,... Also, I can compile the sample program in device/examples. I modified it to be main8051.c, cpu_tools.c, using "reg51.h", only print a message "Hello.\n". It compiled OK. But I loaded to my 8051 borad, it doesn't work. Is it any hints how to fix it ? Or, do you have any simple C program working ?
