Dear Sir,
A basic part of following question that i am going to ask i have already asked on Microzed hardware design and also i got the answer but still i am looking for some more answer as i have to do the same thing for mine ZedBoard Development. Here i am writing the content of uenv.txt file for U-boot:-
Line1-boot_microZed=mmcinfo;fatload mmc 0 Line2-0x3000000 2-${kernel_image}; fatload mmc 0 Line3-0x2FF0000 ${devicetree_image}; fatload mmc 0 Line4-0x2000000 ${ramdisk_image}; bootm Line5-0x3000000 0x2000000 0x2FF0000
Line6-uenvcmd = run boot_microZed
Line7-uenv_boot = run boot_microZed
So here are mine questions:-
1- In Above uenv.txt "boot_microZed" is simply a variable and for example i can replace it(let us say for mine ZedBoard), with "boot_Zedboard". So if i do this then i have to replace "boot_microZed" with "boot_Zedboard" at all the places only in this uenv.txt file, not anywhere else. I want to say that boot_microZed is not a board specific command and it is just simply a variable. If i am not correct please correct me.
2- I do not get why at line 6 and line 7 the command "run boot_microZed" is being called two times in two different variables i.e unvcmd and uenv_boot.
3- what are this unvcmd and uenv_boot variables ? are they board specific? If it is from where i can get the information about it.
Please answer me ????
Regards
Aditya
