![]() ![]() I instrumented the code here in the boot loader and the data read sees certain bytes not matching the kernel byte stream. Its almost as if the Vivado tools are messing up the the flash write of my kernel because the reads are consistently showing the wrong data. The same design starts the bootloader and runs the kernel fine running out of memory its when I try load from flash that the data transferred into memory is wrong. I am reading serial flash data using readbuffer using the example bootloader from Raul's awesome post but I keep seeing the same flips so my kernel is not booting. I am still having issues it seems with writing the kernel binary to flash here for loading the kernel bin file from flash and its driving me crazy.

The cursor stops blinking after 20s but I dont see the kernel load. ![]() I then went ahead and built a device_tree setup and copied this to the Linux kernel tree and built the kernel using a hopefully correct defconfig file but after downloading using xmd I see no output on the console after I start the processor at the correct address. All tests pass, memory tests, hello world etc, all display to the console. Mosaicing into an existing output file is supported if the output file already exists.Built a Microblaze design for Arty and set the serial to 115200. See format specific documentation for legal creation options for each format. Passes a creation option to the output format driver. Multiple threads will be used to process chunks of image and perform input/output operation simultaneously. Use multithreaded warping implementation. Set the amount of memory (in megabytes) that the warp API is allowed to use for caching. New files will be initialized to this value and if possible the nodata value will be recorded in the output file. Set nodata values for output bands (different values can be supplied for each band). Masked values will not be used in interpolation. Set nodata masking values for input bands (different values can be supplied for each band). Use cubic spline resampling (slowest algorithm). Use nearest neighbour resampling (default, fastest algorithm, worst interpolation quality). The datatype of pixels in the source image and destination image buffers. Multiple -wo options may be listed.įor the output bands to be of the indicated data type. Set output file resolution (in target georeferenced units) te xmin ymin xmax ymax: set georeferenced extents of output file to be created. Use this instead of the -order switch.Įrror threshold for transformation approximation (in pixel units - defaults to 0.125). ![]() ![]() The default is to select a polynomial order based on the number of GCPs.Įnable use of thin plate spline transformer based on available GCPs.

The coordinate systems that can be passed are anything supported by the OGRSpatialReference.SetFromUserInput() call, which includes EPSG PCS and GCSes (ie. The program can reproject to any support projection, and can also apply GCPs stored with the image if the image is 'raw' with control information. The gdalwarp utility is a simple image reprojection and warping utility. ![]()
