"BL2: Booting BL31"

Why did you modify ddr_init.c in ATF source code?

It seems that there is DDR controller initialization problem on your target board.

hi @yipingwang 

due to ERROR: mmap_add_region_check() failed. error -22 this error i changed ddr_init.c 

as solution provided in below link

Hi 

static const struct board_timing udimm[] = {
{0x04, rce, 0x01030508, 0x090b0d06},
};

-------------

After change:

-------------

static const struct board_timing udimm[] = {
{0x04, rce, 0x01030508, 0x090b0d06},
{0x0F, rce, 0x01030508, 0x090b0d06},
};

can we flash LS1088ARDB openwrt firmware  on LS1088ARDB-PB?

Please refer to target/linux/layerscape/README provided in OpenWRT to build and deploy the image to the target board.

* u-boot may fail to read MAC addresses from EEPROM on some boards and there
won't be MAC addresses set in environment. This may cause kernel fails to
probe these network interfaces. The workaround is to set MAC addresses
manually, for example,

=> setenv ethaddr 00:04:9F:04:65:4b
=> setenv eth1addr 00:04:9F:04:65:4c
