[U-Boot] Writing files to filesystem

Hi,

I would like to write text files to JFFS2 filesystem from an application launched by u-boot.

I mean something similar to C library functions fopen and fprintf. The purpose is programming a simple logger.

I've been taking a look at the sources and I think fopen and fprintf or similars do not exist in u-boot, only printf and fprintf for stdeer, stdout & stdin.

I've also found logbuff_printk, which writes string to global vector buf[1024]. Maybe this is the best approach to my requirements, not writing to filesystem, just memory storing and printing when required.

Any piece of advice in order to implement that kind of easy logger would be really appreciated.

Thank you very much Ricardo
