Hi everyone,

I’m facing an issue when U-Boot commands are sent one after another without waiting for a prompt. Obviously, device is not able to boot.

Excerpt from logs:

dhcp

=> dhcp

bootloader-commands: Wait for prompt ['=>', 'Resetting CPU', 'Must RESET board to recover', 'TIMEOUT', 'Retry count exceeded', 'ERROR: The remote end did not respond in time.'] (timeout 00:04:56)

Bad Linux ARM zImage magic!

As you see, all commands that were sent between `dhcp` command and until it was able to complete or fail are simply dropped.

Device type config:

{% extends 'base-uboot.jinja2' %}

{% set device_type = "vcu" %}

{% set console_device = 'ttyS2' %}

{% set baud_rate = 115200 %}

{% set interrupt_prompt = 'Press s to abort autoboot' %}

{% set interrupt_char = 's' %}

{% set bootloader_prompt = '=>' %}

{% set uboot_mkimage_arch = 'arm' %}

{% set bootz_kernel_addr = '0x80000000' %}

{% set bootz_ramdisk_addr = '0x83000000' %}

{% set bootz_dtb_addr = '0x82000000' %}

{% set extra_kernel_args = 'ti_cpsw.rx_packet_max=1526' %}

{% set kernel_start_message = 'Welcome to' %}

Device config:

{% extends 'vcu.jinja2' %}

{% set connection_command = 'telnet lava-disp-1.local 7000' %}

{% set power_on_command = 'relay-ctrl --relay 1 --state on' %}

{% set power_off_command = 'relay-ctrl --relay 1 --state off' %}

{% set hard_reset_command = 'relay-ctrl --relay 1 --toggle' %}

Boot action block from job definition:

commands: ramdisk

auto_login:

Have I misconfigured something? What I’m missing? Thanks!
