But the problem is data captured/saved is (RAW 12) 16 bits BIG ENDIAN format.</P><P>When the images are fed into the calibration tool, calibration tools expect data to be LITTLE ENDIAN.&nbsp; I know in all black scene, each pixel is 64. But each pixel in the file is 0x4000.&nbsp;</P><P>There are OV2775 raw images included as examples. And they are little endian. I use 7yuv to verify the endianness of the raw image.&nbsp;</P><P>Why is ISP tool capturing image in BIG endian but ISP calibration tool expects data in LITTLE endian?</P><P>How I can use the ISP tool to capture RAW image in LITTLE endian?</P><P>&nbsp;</P><P>ISP tools is 6.1.22 but newest tool ISP tool 6.6.23 has same problem.</P><P>&nbsp;</P><P>&nbsp;</P><P>&nbsp;</P><P>&nbsp;</P><P>&nbsp;</P><P>&nbsp;</P><P>&nbsp;</P> Tue, 14 Jan 2025 07:25:06 GMT https://community.nxp.com/t5/i-MX-Processors/IMX8MP-ISP-tuning-tool-raw-data-endianness/m-p/2027353#M232971 jjiimmyy 2025-01-14T07:25:06Z https://community.nxp.com/t5/i-MX-Processors/IMX8MP-ISP-tuning-tool-raw-data-endianness/m-p/2028025#M233007 <P>yes, this is exist issue, customer need convert it by themselves now, VSI would align them later</P> Wed, 15 Jan 2025 06:20:47 GMT https://community.nxp.com/t5/i-MX-Processors/IMX8MP-ISP-tuning-tool-raw-data-endianness/m-p/2028025#M233007 joanxie 2025-01-15T06:20:47Z
