i'm using iMx6 Quad core, a Linux 3.035 and i would like to configure my eMMC in HS200 mode.
I back-ported HS200 patch (linux-2.6-imx.git - Freescale i.MX Linux Tree) but i had to adapt it (as my linux is 3.035)
When running the code i get an error -EBADMSG coming from mmc_switch when having call:
mmc_switch(card, EXT_CSD_CMD_SET_NORMAL, EXT_CSD_HS_TIMING, 2, 0)
DO you have idea on why this message is not recognized ? Am i missing another patch to back-port ?
Thanks for your help
