Hi Friends I need to make MTD partition followed by JFFS2 file system on 32 MB NOR flash of one of the ARM926-ejs based board.I am using linux kerenel version 2.6. I didn't get information about 1,How can i create MTD partition ? 2,Do i need to have MTD utilities ? 3,If yes what are the steps to integrate it ? 4,How can i implement JFFS2 on MTD partition? can i achieve above from u-boot promt? I would appreciate your guidence /documentation that shows me entire procedure to get me going on this stuff. -- Thanks & Regards Harsh

[U-Boot-Users] stand alone application
by kow9loon 01 Apr '07

01 Apr '07

I am trying to write a stand alone application, which is supposed to be a board diagnostics for manufacturing. The way it supposes to work is as follows: U_boot could either download the diagnostics manually under the U_boot prompt, or be calling up do_tftp() directly if it is to be done automatically. Results generated from the diagnostics are to be recorded in the RAM, whose contents shall later be uploaded as a log file to an external server via tftp. After reading the examples provided in the example directory, I have the following questions: (1) In my understanding, the stand alone application (the board diagnostic for manufacturing) is supposed to be compiled as a separately entity in the U-boot path and then be placed in an external server, waiting to be downloaded to the RAM on board; when either go <address> or do_go(address) is executed, control get passed to the stand alone application, how could the stand alone application be able to make calls to functions that are exported (those appeared in both exports.c and export.h), without some kind of "linking"? Unless go <address> or do_go(address) perform some sort of "linking" or "peudo linking" action, this doesn't sound possible. Could someone explain to me how this works? My expectation of how this could work is: on execution of the go <address> command or do_go (address), address of the jump table is to be loaded into a register, and it is the responsibility of the application to save the value of this register before anything else, in such a way to allow the application to call up functions that it elects by picking up the correct addresses of these functions via indexing. However, after reading the examples provided in U-boot, I have not seen any motion of saving the value of the register. However, vwhich register U-boot chooses to use would be processor dependent. This is just my two cents. (2) Is uploading currently being supported in U-boot's tftp implementation? Judging from the do_tftp codes, it looks that only "downloading" action is supported not "uploading". Could someone confirm that or point to the place where "uploading" is implemented? Any input would be greatly appreciated. Thanks.
