Hi All,
Every once in awhile I get this "Timeout waiting for hardware
interrupt" error. This is with a uSD on a zynq ultrascale board
running a 5.2.10-rt5 kernel (PREEMPT RT is enabled). The device tree
entries are:
/* SD1 with level shifter */
&sdhci1 {
status = "okay";
no-1-8-v; /* for 1.0 silicon */
wp-inverted;
xlnx,mio_bank = <1>;
};
and
sdhci1: mmc@ff170000 {
compatible = "arasan,sdhci-8.9a";
status = "disabled";
interrupt-parent = <&gic>;
interrupts = <0 49 4>;
reg = <0x0 0xff170000 0x0 0x1000>;
clock-names = "clk_xin", "clk_ahb";
};
Maybe someone sees something.
thanks,
Paul
