Hi, I began to test Yaffs on a 2Mb empty partition, with a little program that recursively writes and erases files (one of 500*1024 bytes and many of 1024 bytes). I let it turn during approx. 15 min. Then, I wanted to format my yaffs partition with mkyaffs, ... but once executed, it tells me a lot of damaged blocks...! Then, when I remount my partition, It's like none files had been erased... I've only 176 kB now ! So do you have an idea of what could I do to *really* format my 2Mb partition, in order to my empty 2Mb again ? Many thanks. Regards. Ludovic.
