hi good day, We are using codevision AVR as compiler for atmega128 , and bootloader(upper 2K) for loading application firmware(start from 0x0000 , size nearly 70K) and a separate data structure(start from 0xB400, size nearly 20K). Now we want to access that data structure from our application firmware.Actually we failed to access the upper 64k area by declaring a pointer to...

Hi, I'm preparing a system with a Raspberry Pi as an embedded computer, running the Buildroot compiled Linux. To extend possible boot options I have to use additional bootloader (barebox or u-Boot). Everything works fine, however it appears, that this intermediate bootloader needs to pass the original kernel command line parameters, which are prepared by the start.elf tool. Of

I am using intel PXA flash chip to store embedded bootloader and embedded App. It is taking long time (4 minutes) to write 3 MB data. I am writing 128k block at a time. It is taking 10 seconds to read. Any suggestions on improving the speed to write is appreciated. I am new to flash programming. Or is it expected time? Did we select wrong chip for writing such large data. I am designing to...

Hi, I am a newbie in the embedded system world. Currently, I got a development board with StrongARm 206MHz CPU. I got the vivi and the cross compiler and prepared to compile a bootloader for my embedded system, However when I run the "make" command /opt/host/armv4l/bin/armv4l-unknown-linux-gcc -I/root/cheong/gsl/linuette/vivi/i nclude -I/opt/host/armv4l/include/ -Wall -Wstrict-prototypes -O...

I am running Linux 2.6.26 on a PPC. I want to boot linux without using a bootloader to speed up the boot process but, due to the size of the kernel, I cannot put it at the reset vector. I was told that I have to put a branch instruction at the reset vector location and branch to the location where my kernel is. How do I put a branch instruction at the reset vector?
