I thought that the section 1 might be obsolete. With the documentation of my RPXlite, I have'nt found any VisionClick flash programmer. About the documentation link you've sent me, I read everything except the ELDK section. I did compile a u-boot, u-boot.bin, and everything without any error messages. (Compiler used is 2.95.2, just in case). Before writing everything into the flash memory, I wanted to test it by loading it into the ram and execute the binary file. ( the same way I do when I want to run linux on the box, I load a kernel at 0040 0000, and then run the code starting at 0040 0000 or 0041 0000 (when the 64k ELF header is not stripped)). And as for the u-boot binaries, they do not want to run, and I get no error message, my RPXLite either reboot or freeze. I also tried the u-boot.srec, just in case the S-record image would run better, but it did'nt. I guess that's why I'm looking for someone who could give me a few hints about how to run u-boot. As I understand it (and maybe this is where my problem is) I am supposed to be able tu run u-boot's binary (or s-record image) directly from the ram. Now, this task seems impossible to me. I even tried to run the elf binary in the linux box that I have made (mounted via nfs) and it crashed (Segmentation fault error only) I know these questions might sound "newbee" to you guys, but I really need to know if this code is suppose to work alone, without any kernel, or it absolutly need to work under linux (a bit like when you run lilo from a "normal-i386" linux box) I thank you a lot for your time, this is really helpful. Like they say, the firsts steps are always the hardest and theses are my first in the embedded world... Rapha?l
