Hi, all
I am a student in Beihang University in Beijing, P.R.China. I just started to learn to build a system uClinux on Microblaze. I m reading a document named uClinux_ready_Microblaze_design_1_05_a.
I met a problem. My target board is just ML401, using EDK 8.1 as told in the doc. I strictly followed the steps and everything seems going smoothly, until the last step of downloading kernel image to the target board. Still there are no errors both in the XMD command line and board. There is no uClinux bootup infos in hypertrm either. I wonder whether there is any error with the kernel image or there are any other errors.
Maybe some of the questions are silly. Thanks very much for your patient of reading through my e-mail. Hope u can help me.
