2 Replies and 1344 Views Kernel 2.6.19-rc1 for PXA270  1344  2 Started by  clibux I am working to compile the 2.6.19-rc1 kernel for a PXA270 development board. The sample kernel and file system from Logic successfully run on the board. With that in mind, I am using the sample image config file in combination with the lpd270_defconfig included with the source to configure the kernel. The intent is to use the file system installed on the flash from the sample system with the newly compiled kernel. There are some differences between the config files, and some problems. The ...

1 Replies and 1371 Views DMA under Linux anyone?  1371  1 Started by  burelllil Hello, I am trying to make DMA transfers on an M5485EVB under Linux, with zero success atm. My goal is to use the DMA to transfer data from/to the DSPI. The problem I am having is dual (or -2 does not work because of -1): -1) When I call MCD_startDma, the processor freezes shortly after, for a long duration (like 10-15 secs). After that delay, the execution continues. MCD_dmaStatus returns immediately 6 (DMA_DONE), but of course nothing has happened, even if I use mem-to-mem transfers (also, ...

1 Replies and 1348 Views Does the Logic Linux BSP support virtual memory  1348  1 Started by  jpinakis Hi, This may seem like a somewhat naive question, but I haven't been able to find a definitive answer anywhere so maybe someone here can help. Is Logic's Linux BSP based on uCLinux And if this is the case, and we build it for a Coldfire M5485EVB (which has an on-board MMU) then do we get virtual memory, or does it disable the MMU Thanks, james
