hi,
use uboot202004
#define DSRC_PRI_RSTn IMX_GPIO_NR(4, 22)
int ret=gpio_request(DSRC_PRI_RSTn, "DSRC_PRI_RSTn");
printf("gpio_request: %d \n", ret);
error: gpio_request: 3
use uboot2018 is ok,return ret is 0;
Hi grayli_wang
one can try to rebuild all from scratch using scfw v.1.7 SCFW Porting Kit
https://source.codeaurora.org/external/imx/uboot-imx/tree/?h=imx_v2020.04_5.4.70_2.3.0
Best regardsigor
use scfw1.7.0 + uboot202004 is fail .
return 3
