What is 'erase block' in `mkfs.jffs2' utility in Linux? -


mkfs.jffs2 What's the 'erase' block in the utility?

I can not get anything by googling, maybe because of my lack of skill, can someone tell me what is this?

Can anyone tell if 'erase'?

JFFS 2 runs on raw flash, not on devices such as USB sticks which have firmware that make them traditional Looks like discs. Raw nand flash can be erased in very large blocks (i.e. set bits to 1). The "deleted block" is the size of a block that the device can erase. See

/ proc / mtd to see what your system thinks is the removable block size of each device (you need to use an MTD (/ proc / mtd) Memory technology device, i.e. raw flash) device will be required and JFFS2 will be useful.)

python - Assemble mpeg file unable to play in mediaplayer -

I am currently working on a school project and I think that is to gather some problems with the MPEG file I The scope of my project is: 1) Split the MPEG file into pieces of many fixed sizes. 2) Collecting some of them and leaving some part. Problem 1: When I run the file in the media player, it will play the video until it reaches that segment which I left Give it Example: Chunk = ["yui_1", "yui_2", "yui_3", "yui_5", "yui_6"] Duration of each segment: 1 second * If you think I have left the "yui_4" section. * If I went to collect all the parts except "yui_4", then the video will play the first 2 seconds before being hanged throughout the period. Problem 2: When I gather the first part off the part, it is unable to run the full MPEG file is. Duration of each piece: 1 second Example: wheel = ["yui_2", "yui_3", "yui_4", "yui_5", "yui_6"...
