#160286 - Bootloader |
Hi Dear All,
I'm doing my own bootloader (using C language) and on my board i have x2 32kB SRAM and I'm using AT89C52 MCU. I have tested my board using PAULMON2. It function well. I able to download my application code to SRAM and run the application code just hand coded to ljmp address and run it. So, now my problem is in my application code i can't add interrupt function (eg. Serial-Interrupt, Interrupt service routin ) code in because once i add in then will not working already. I have do the testing, if i using my bootloader and the application code using standard serial library <stadio.h> like printf(), putchat(), and so on...It working fine. I think most possibility is the bootloader problem because when i using PAULMON2 to download the application code. The application code work fine. Once i use my own bootloader then can't. Why i can't use interrupt function in my application code. How to solve the problem? Please can you advice what can i do? Thank you, Bc |
