imx7 mfgtool error Verifying Checksum ...Bad Data CRC

delauratfrançoi — Thu, 03 Dec 2020 13:50:32 GMT

Hello

I work with imx7d.

I use mfgtool to update my board. I use the L4.9.11_1.0.0 mfgtool. I tested the timing of the ddr. It is OK.

But I have an error whan the u boot mfgtool verify the fsl-image-mfgtool-initramfs-imx_mfgtools.cpio.gz.u-boot. The error is "Verifying Checksum ...Bad Data CRC".

The size of fsl-image-mfgtool-initramfs-imx_mfgtools.cpio.gz.u-boot is bigger than 8Moctet.

If I use a old fsl-image-mfgtool-initramfs-imx_mfgtools.cpio.gz.u-boot with a size smaller than 8Moctet it is ok.

I saw that only 8Moctet was loaded if the size was bigger than 8Moctet

I don't understand.

Can you help me please.

Best regards.

François

Hi François

one can try to decrease size of fsl-image-mfgtool-initramfs-imx_mfgtools.cpio.gz.u-boot

rebuilding it (remove unused drivers from image) using sect. 6.2 Manufacturing Tool Yocto Guide

included in Documentation

Best regards

Yes I decreased the size of fsl-image-mfgtool-initramfs-imx_mfgtools.cpio.gz.u-boot. I remove the package mtd. And there is not mode error crc.

But I would have liked to know why I am limited to a size of 8M.

Best Regards
