Hi,

I have built a kernel using the defconfig at configs/nuvoton_nuc976_tomato_defconfig for the nuvoton tomato, I am trying to load it from an sd card but get an error verifying the checksum

I seem to be getting an issue when I am building an image for the NUC980 using the nuvoton_nuc980_defconfig.
Building the image without creating an image build to the end, but when "ext2/3/4 root filesystem" is enabled, it fails.

Hi ,
I use 977 mcu,below is my step
1.make nuvoton_nuc977_defconfig
2.make and generate uImage
3.I burn in board ,I can see boot kernel can occurpt some error

Hello Everyone, Please help mee

• I activate CAN0 Pins, IP route2 and CANUTILS from the kernel. I boot the device and turn it on. but when I do Candump can0 the message does not come. The cansend command does not work either. I examined it with an oscilloscope. There is no hardware problem.

Hello,
I built file system using Buildroot. And I've uploaded it to SD card. Rootfs started working but I don't have any users. And I can't log in to user-root.
Why couldn't System log in to user-root?
And How do I log in to any user?

Buildroot is missing defconfig files for individual NUC980 boards. It looks like different dev boards have different boot strategies, requiring u-boot to be built on a per-board basis. None of this is documented anywhere, and there's only one "nuvoton_nuc980_defconfig" file that's not clear about which board (IoT? EVK? Serial server?) it supports since it only uses the "nuc980" u-boot config, which (I think?) targets parallel NAND flash booting.

I have 2 partitions on the sd card, 1 with the uImage (formatted fat32) and one with the rootfs (ext4). But when i do

fatload mmc 0:1 0x7fc0 uImage 
bootm 0x7fc0

The kernel panics because it can't load the rootfs. When i supply bootargs set bootargs root=/dev/mmcplk0p2 console=ttyS0,115200n8 rootfs=ext4 the boot process hangs and I don't see any output on the console. The mmc drivers are enabled in linux-menuconfig

If I boot from a kernel with initramfs I don't see any mmcblk device under /dev/

Hi,
I wana upgrade my nuc972 project so I cloned uboot and kernel from this.
I used default configuration on uboot and kernel.
I made uImage by below script

#!/bin/bash
MKIMAGE_TOOL=$UBOOT_DIR/tools/mkimage
$MKIMAGE_TOOL -A arm -O linux -T kernel -a 0x7FC0 -e 0x8000 -d 970image 970image.ub

I tried to run it on nuc970-evb.
It hang when starting kernel.

what's wrong?

Hi,

It would be great if we could have one defconfig which could generate ubi image so that we do not need to make the ubi img manually by mkfs.ubi and uninize.

I am trying to do it but met some problems.

Tibalt

Dear team,

I am using buildroot for new product in our company, all things solved successfully with a "make" command, but currently, we want to the buildroot generate a MP flash image directly without using WINDOWS MP application. Could you add this feature to buildroot or leave a NUC97x Flash image format with us?

Thanks!

Br,
Xiangyu

When Buildroot tries to build package host-m4-1.4.17 I get this error:

This looks similar to this issue:

I have glibc version 2.29 installed.

hi nuvoton

NuMaker-HMI-N9H30

Added QT in make menuconfig .
When I run the QT program on the board

line 1: syntax error: unexpected word (expecting ")")

How can I make the QT program work?
please help

thank you

In NUC972 neither i am able to burn files in any of flash mode nor eras previously burned files in nuc972. Please guide for same. Thank you.

Any possible solutions ?

I took the latest configuration OpenVPN 2.5.0 and libopenssl 1.1.1i from the original image of GitHub buidlroot, and found a problem. After OpenVPN is started, when run to TLS_ctx_client_ new(new_ctx); in SSL. C file, it will be stuck ,Sometimes it takes 5 minutes or 20 minutes to get out, sometimes it takes an hour, and then it runs normally. I find that this function goes into libopenssl to do initialization work. I don't know why it's stuck.
In addition, I think the above lib may not use the encryption hardware acceleration of nuc972. What should I do if I want to use it?
who can help me?
Look at the time in bold below. There's a difference of 17 minutes。

I'm trying to build for the tomato (using nuvoton_nuc976_tomato_defconfig) with initramfs disabled. the build progresses for a while before failing. Not sure what this error means

I'm trying to make use of the QEMU library to run some pre-compiled binaries on the NUC980, but I keep running into the below error when I try to make use of any Linux user-land emulation.

The kernel compiles and boots successfully when QEMU systems emulation is enabled instead. Has anyone encountered a similar issue? Is there another module or library which needs to be compiled to enable this feature?

Following on from #20 the kernel doesn't start.

A fresh flash of uboot causes the first attempt at booting to cause this repeating message

After resetting the board it then hangs after detecting the flash

Command to make the image:

mkimage -A arm -O linux -T kernel -S sha1 -a 8000 -e 8000 -d linux.bin.gz uImage

Hi,

Package e2fsprogs need to backport from buildroot upstream, glibc 2.27 will have a copy_file_range library call to wrap the new copy_file_range system call, this conflicts with the function in misc/create_inode.c; that would cause compile error when enable this package on target board.

Thanks.

When building alsa in Buildroot, automake fails with the error: "Unescaped left brace in regex is illegal here in regex"

This is because recent versions of Perl (I'm on 5.26) don't support unescaped braces. The solution is to modify line 3936 of automake from this:
$text =~ s/\${([^ \t=:+{}]+)}/substitute_ac_subst_variables_worker ($1)/ge;
to this:
$text =~ s/\$\{([^ \t=:+\{\}]+)\}/substitute_ac_subst_variables_worker ($1)/ge;

I've added connman package to the build so i can get ethernet working but the Tomato doesn't boot and is stuck.

nuc980dr 64pin的nand控制器少了r/b引脚，该怎么使用nandflash呢？

Hello,

I am developing software on NUC980 series microprocessors on embedded linux software. I want to request technical support from you. I want to boot via eMMC/MMC with Buildroot available in your Github account. Can I get technical support from you for this?

I'm having a few issues downloading mmc support from device drivers via u-boot. Could it be a problem with the U-Boot version or the Linux Version?

Dear sir:
I am using buildroot to generate rootfs image for a 980 dev board. The 980 MPU boot from a spi nor flash w25q256. The uboot and kernel seem to be ok from the message printed. But the rootfs from buildroot seem to be wrong."**devtmpfs: error mounting -2". It puzzled me for a long time. And I tried several version of buildroot, no one worked on the board. Please give me some advice on this issue. Thank you very much!

Hi, My Chili board is using the following kernel version

Linux (none) 4.4.289 #7 PREEMPT Thu Mar 21 14:54:56 CST 2024 armv5tejl GNU/Linux
And I type in ifconfig will find RX dropped too large, I think this is a problem. How can I solve this to avoid this isseus happening?
Do I need to update the network driver?
attached boot log

Thanks

I try to build a new image with realtek 8188 wifi support, but i get some errors.
Then try to build a more complex realtek chipset RTL8821, and this is builded without errors. I like to use 8188. Any suggestion to build?

Hi there. I have a custom board with the TLK110PT PHY chip and am having trouble getting things running.

I am using the iot defconfig to build, and I've enabled the default TI PHY drivers. Is there anything else you would suggest?

How do I enable MDIO tools to debug?
Thanks.

Hi,
I change nand flash from S34ML01G1(ECC-1) to S34ML01G2(ECC-4).

I test bad block on u-boot, no bad block.

but when booting kenel, it faces pannic on ubi filesystem.
i made ubi image by buildroot.
this is config view.

this is ubinize.cfg

this is kernel booting log

=> run bootcmd

What's wrong? make ubi image?

//foo.get();
