Pocket PC Forum / Developers / Test Tools / July 2008How to test MLC nand flash wirh WinCE r2 Cetk
Hi,all For the MLC Nand flash ,there are 2048 bytes in a sector.But I find the CETK source code "#define DEF_SECTOR_SIZE 512 "for the test of nand . So I always get the following output: FAILED: DeviceIoControl(0x00531503, DISK_IOCTL_WRITE) failed error 87 FAILED: DeviceIoControl(0x00531503, IOCTL_DISK_WRITE) failed error 87 FAIL in C:\yzqasp1\private\test\BaseOS\Drivers\Storage\Function\flshwear\.\flshwear.cpp at line 76: Dsk_WriteSectors(); error 87 FAIL in C:\yzqasp1\private\test\BaseOS\Drivers\Storage\Function\flshwear\.\flshwear.cpp at line 291: ReadWritePerf() How to test the MLC nand ? Thanks > Hi,all > [quoted text clipped - 12 lines] > > How to test the MLC nand ? Thanks hi,the problem I encounter is similar to yours...i want to access nandflash from Mass storage driver. I use the handle returned by api OpenStore() and send IOCTL_DISK_READ cmd to nand driver,but it always complains invalid parameters.. can anyone show me some hints? This is a test issue that was fixed in a 6.0R2 CETK QFE. The handle returned by OpenStore() is routed to the flash driver, which does not understand the DISK_IOCTL_WRITE/IOCTIL_DISK_WRITE ioctls. Instead it requires flash-specific IOCTLs, documented here: http://msdn.microsoft.com/en-us/library/bb821589.aspx The updated version of the flshwear test takes an optional "/flash" flag, which forces the test to use the IOCTL_FLASH_* ioctls instead. An example commandline would be: tux -o -d \release\flshwear.dll -c"/disk DSK0: /store /flash" In addition, the updated test will use the actual sector size of the flash part, instead of a hardcoded value. Thanks, and let me know if you have any questions! --Vadim Yushprakh On Apr 24, 2:35 pm, "Eva" <dhua...@hotmail.com> wrote: > Hi,all > [quoted text clipped - 12 lines] > > How to test the MLC nand ?
