Arria 10 Linux Kernel

[JoshuaWillson]

Hi All,

I am trying to boot (linux-socfpga) linux kernel on the Arria 10 SoC. 

Does any one have any knowledge on which tools chains need to be used for which versions of kernel. 

When I build ACDS20.1 (https://github.com/altera-opensource/linux-socfpga/tree/ACDS20.1_REL_GSRD_PR) with tool chain gcc-linaro-7.5.0-2019.12 (arm-linux-gnueabihf) I can get my build to boot.

When I build ACDS21.1 (https://github.com/altera-opensource/linux-socfpga/tree/ACDS21.1_REL_GSRD_PR) with tool chain gcc-linaro-7.5.0-2019.12 (arm-linux-gnueabihf) I can NOT get my build to boot.

Do I need to change the following compatible line in the DTS? 

model = "Altera SOCFPGA Arria 10"; 

compatible = "altr,socfpga-arria10", "altr,socfpga";

Does anyone have any info on this?

Thanks!

Hi Joshua,

I will check your request on compatible line in the DTS.

I will come back to you soon.

Thank you,

HI Joshua,

May i have the following item:-

1 What board are your use (Intel dev of Arrow dev, custom board)

2 What design are using (GSRD, ref design)

3 Any hardware modification

4 Software modification(uboot, linux kernel)

5 do you have error log ?

Thank you,

Aliff

1 What board are your use (Intel dev of Arrow dev, custom board)

     Answer: Terasic HAN Pilot Platfrom Arria 10 SoC

2 What design are using (GSRD, ref design)

    Answer: GHRD that Terasic points too in following link https://www.terasic.com.tw/cgi-bin/page/archive.pl?Language=English&CategoryNo=216&No=1133&PartNo=4#contents REVF

3 Any hardware modification

     Answer: Adding in soft IP TSE design, w/ MSGDMA, HPS i2C, and pio for connecting a design w/ SFP modules

4 Software modification(uboot, linux kernel)

     Answer: 

        uboot: v2023.10

        linux kernel: Linux version 6.1.38

5 do you have error log ?

    Answer: 

        No error log: Could not even get the kernel to boot. But this is where it stops:

            Starting kernel ...

           Deasserting all peripheral resets

Please note: 

For any one with the same problem it came down to the DTB. Im not sure what part exactly from the DTB the kernel did not like but I had different versions of a DTB from example designs and the one that worked was the DTS from a10s_tse_example_design from rocketboards. I was using the DTS from the compiled DTB from terasic that came with the development board and that one was causing issues. 

MY assumption is there was some peripheral that the kernel could not talk too (i2C, spi, etc) that was hanging the kernel.

Hi Joshua,

Can you share all your booting log?, it might have information's there.

Thank you,

Hi Josua,

Currently I tried the https://www.rocketboards.org/foswiki/Documentation/BuildingBootloaderCycloneVAndArria10#Cyclone_V_SoC_45_Boot_from_QSPI

but what i encounter is the error during linux compilation.

After I manage to compile successfully I encounter the board is no boot.

I still working on it, give me some time

Thank you,

Aliff

Hi Joshua,

For workaround, can you try this step https://www.rocketboards.org/foswiki/Documentation/Arria10SoCGSRD?erpm_id=11789423_ts1698043860867#:~:text=FPGA%20configuration%20file-,Setting%20Up%20Yocto%20Build%20System,-1.%20First%2C%20make

For me the step will give me no error.

Thank you,

Aliff

Hi Joshua,

can i have update from the work around?

Thank you,

Aliff

I had to go through my DTS and make sure there was no peripherals that were instantiated that the Kernel could not connect/talk too. When it attempted to "Dessert All Peripherals" it would just hang.

Hi Joshua,

Apologize for being lates as im sick leave.

Can you share your DTS here?.

Hang issue also can cause from hardware side.

Thank you,
