Subject: eMMC probe in imx8mm
Date: Fri, 5 Jul 2019 14:04:08 +0000 [thread overview]
Message-ID: <14d5d82d-ddb0-89e2-84c0-00cb980dda2a@data-modul.com> (raw)
Hello everyone,
I have brought up Barebox on imx8mm-evk board. Barebox is programmed on SD-card.
In the Barebox console, when I probe eMMC, I will receive I/O error.
Therefore, similar to the imx8mq device tree, I added clk node to assign
clock-parent and clock-rates of the assigned clock of the eMMC (usdhc3):
&clk {
assigned-clocks = <&clk IMX8MM_CLK_USDHC3_ROOT>;
assigned-clock-parents = <&clk IMX8MM_SYS_PLL1_400M>;
assigned-clock-rates = <200000000>;
};
Now, eMMC probe works and eMMC is detected. But when I want to boot from eMMC,
Loading ARM aarch64 Linux image '/mnt/mmc2/Image' takes about 13-14 seconds!!
Does anyone have an idea where is the problem? It would related to the clock,
but which part?
Best regards,
Reyhaneh
