It manifests like the description in Bug 1001764 - Enhancement of MMC/SD over SPI driver. The zip contains an ecm file, code, and all patches used. When the application is run, a loop will open a file on an SD card, develop strings with snprintf, write them to the file, flush the filesystem, and close the file. When it is run, the problem always occurs when the variable "dev" in the SPI code is 0xFFFFFFFF and results in an exception 5. It has to be run for many minutes to cause failure, but typically it will fail in less than 10 mins. Ilija, If you have time to run this, it might eliminate or confirm if the problem is related/unrelated to hardware reliability. Once we know it is not related to bad hardware, perhaps we can form some theories about the cause of the exception. Please note that all I2C code is commented out, so this only uses FXM and SD card and should run on any FXM hardware with SD support. I ran it on a K60 100Mhz, so there is no cache. I have disabled the cache in the ecm as well. I put the attachment here rather than the SPI bug because I cannot reproduce it on non-FXM hardware. If it really is a MMC bug, we can move it. -- You are receiving this mail because: You are on the CC list for the bug.
