Hi!
I have the same problem as:
http://lists.infradead.org/pipermail/linux-arm-kernel/2012-March/091529.html
Read/write speed of SDHC card is very slow.
Kernel 2.6.35 from Freescale works with a excellent SDHC performance.
Mainline kernels from 3.17 to 4.9.5 works very slow with SDHC.
Is there any solutions about this problem?
Hi Maxim
there are number of eSDHC errata which should be carefully
implemented to achieve good performance
http://www.freescale.com/files/dsp/doc/errata/IMX25CE.pdf
Unfortunately there is no nxp(fsl) i.MX25 support for new kernels
and you should implement this yourself or consider some mss services
like Pro-Support www.nxp.com/prosupport .
Best regards
igor
