Boot for nuvoton_nuc980_chili_defconfig fails

[MrutyunjayPatel]

hi, we built the buildroot with following .

make nuvoton_nuc980_chili_defconfig make

Then using files from MA35D1_Buildroot\output\images folder

/-/ NuWriter.exe on PC.
Select DDR parameter is “NUC980DR61YC.ini”. And then, press “Continue” button.

1. Image Name: u-boot.bin >> Image Type: Loader >> Image execute address : 0xe00000 PROGRAM/VERIFY
2. Image Name: uimage >> Image Type: Data >> Image execute address : 0x200000 PROGRAM/VERIFY
3. Image Name: env.txt >> Image Type: environment >> Image start offset address: 0x080000 PROGRAM/VERIFY
   4. Image Name: nuc980-chili.dtb >> ?? >> ??

we used env.txt from 4.4 BSP as the MA35D1 did not have this file !!!!!!!!

what should we do with .dtb file where to write ??? it and execute address ???.

The env.txt file needs to be copied by the user from the user manual and modified according to their specific needs. Below is a reference for env.txt, which also includes information about burning the device tree blob (dtb) ==>

baudrate=115200
bootdelay=1
stderr=serial
stdin=serial
stdout=serial
setspi=sf probe 0 30000000
loadkernel=sf read 0x07fc0 0x200000 0xA00000
loaddtb=sf read 0x1400000 0x1C0000 0x20000
bootcmd=run setspi;run loadkernel;run loaddtb;bootm 0x07fc0 - 0x1400000

The CRC error issue you are experiencing might be caused by an incomplete loading of the kernel image. Please check if the length of the SPI read kernel is greater than the size of the kernel image.

hi , Thanks for the reply , I am new to the buildroot toolset.

we did not find any documentation for nuc980 chill board for linux kernel 5.10

we tried images for linux kernel 4.4 its ok we could build images and boot the image, I build on the provided Virtual pc.

Please Can you post the correct nuwriter files settings to be written at address and execution address for the default "nuvoton_nuc980_chili_defconfig" configuration .

we dont know the internal setting to be used as per chilly defconfig built images.

1. Image Name: u-boot.bin >> Image Type: Loader          >> Image execute address       :  0xe00000 PROGRAM/VERIFY
2. Image Name: uimage      >> Image Type: Data              >> Image execute address       : 0x200000 PROGRAM/VERIFY
3. Image Name: env.txt       >> Image Type: environment >> Image start offset address  :  0x080000 PROGRAM/VERIFY
4. Image Name: nuc980-chili.dtb >>  Image Type: Data    >>  ???????                               :  0x??????? PROGRAM/VERIFY 

and the correct env.txt file for the default build.

as I said I used the env.txt and address settings from chill boards kernel 4.4 documents they may not be applicable correctly to kernel 5.10 builds images .

Thanks and regards mrutyunjay

I have post the content of env.txt for linux-5.10. Please have a look at the content. Again ==>

baudrate=115200
bootdelay=1
stderr=serial
stdin=serial
stdout=serial
setspi=sf probe 0 30000000
loadkernel=sf read 0x07fc0 0x200000 0xA00000
loaddtb=sf read 0x1400000 0x1C0000 0x20000
bootcmd=run setspi;run loadkernel;run loaddtb;bootm 0x07fc0 - 0x1400000
~~

The 'loaddtb=sf read 0x1400000 0x1C0000 0x20000' has answer your question.
.dtb can be programmed to SPI offset 0x1C0000 and load to DDR 0x1400000.

[ychuang3]

I notice your uboot message:

SF: 8388608 bytes @ 0x200000 Read: OK

==> That means you load 8388608 bytes from SPI to DRAM for kernel image.

But, the uImage message says that kernel size is 9089168

Image Name: Linux-5.10.140
Image Type: ARM Linux Kernel Image (uncompressed)
Data Size: 9089168 Bytes = 8.7 MiB

That is, you load only 8388608 of 9089168 bytes only. That's why u-boot complain about CRC error. Looks like the loadkernel setting of your env.txt be:

loadkernel=sf read 0x07fc0 0x200000 0x800000

Please modify the last 0x800000 as 0xA00000 to fix boot failed issue.

hi , after doing the changes as mentioned 980 chili board boots kernel 5.10 images

for reference to future users
