Blinky basic application not loading in uboot for the same load address as hello world in NXP based iMX8MP boards #98042
Description
Describe the bug
I have configured unused gpio in A53 dts like below
aliases {
led0 = &myled0;
};
leds {
compatible = "gpio-leds";
myled0: led_0 {
gpios = <&gpio4 20 GPIO_ACTIVE_LOW>;
};
};
During compilation time no issue but while loading in uboot it is hanging .I have used below commands for loading in uboot.
fatload mmc 0:1 0x40000000 zephyr.bin
dcache off; icache flush
go 0x40000000
the same commands works for fine for other applications but for blinky appliaction its hanging
