Hi Fabio,
Force clock on did help us fix some issue, like voltage switch for UHS card. According to your commit log, seems this patch affect the booting time, do you mean the API readx_poll_timeout() cost a lot time? Can you show us the detail info about booting time effected by this patch?
If I revert the patch SPL/U-Boot boot in one second.
With this patch, it takes around 20 seconds, which is unacceptable.
Is your target success to boot finally after 20sec? I didn't have target to use fsl_esdhc_imx driver.
If booted after 20sec, how about below code?
#ifdef CONFIG_FSL_ESDHC_IMX_TIMEOUT #define FSL_ESDHC_IMX_TIMEOUT CONFIG_FSL_ESDHC_IMX_TIMEOUT #else #define FSL_ESDHC_IMX_TIMEOUT 0 #endif
ret = readx_poll_timeout(..., FSL_ESDHC_IMX_TIMEOUT); if (FSL_ESDHC_IMX_TIMEOUT && ret) pr_warn("...");
If there isn't other issue,
Best Regards, Jaehoon Chung
Thanks
