Hi, I'm trying to periodically write to flash on a small embedded device I'm playing with. I want to sync a buffer to flash every 15 seconds if it's dirty. I'm using a 2.4.20 kernel(not my choice) and have connected my buffer_write routine to a kernel timer both directly and also via a tasklet initiated by a kernel timer. Both methods give me an oops when attempting to write the flash. Is there anything basically wrong with this method? Will MTD_WRITE not function in interrupt context? It works just fine when called from an ioctl.
Hope you can help
