LS1043A-RGW secondary CPUs fail to come online

andrewbarrow — Fri, 23 Mar 2018 20:42:51 GMT

I'm running LS1043A-RDB firmware I built with the LSDK, with hand-edited DTB file. The secondary CPUs fail to come online at boot. This happens with either 4.4 or 4.9 kernel.

I boot by U-Boot loading image and the DTB from SD card.

NAND contents are the same as the RGW board comes with.

Am I missing a firmware image? Do I have a bad DTB?

It looks like that your DTB file is incorrect. Test your board using default version of the LS1043ARDB LSDK DTB file.

Have a great day,

Re: LS1043A-RGW secondary CPUs fail to come online

andrewbarrow — Mon, 26 Mar 2018 22:38:45 GMT

Here are some notable differences in the .dtb files that boot on one cpu only vs. fail to boot:

Default LS1043ARDB LSDK file: fsl-ls1043a-rdb.dtb - boot freezes prior to CPUs coming online:

interrupt-controller@1400000 {
   compatible = "arm,gic-400";
   #interrupt-cells = <0x3>;
   interrupt-controller;
   reg = <0x0 0x1401000 0x0 0x1000 0x0 0x1402000 0x0 0x2000 0x0 0x1404000 0x0 0x2000 0x0 0x1406000 0x0       0x2000>;
   interrupts = <0x1 0x9 0xf08>;
   linux,phandle = <0x1>;
   phandle = <0x1>;
};

firmware {

   optee {
   compatible = "linaro,optee-tz";
   method = "smc";
};

My .dtb, based on ls1043a-rgw DTB image for OpenWRT pre-compiled binary (boots, but secondary CPUs do not come online):

interrupt-controller@1400000 {
   compatible = "arm,gic-400";
   #interrupt-cells = <0x3>;
   interrupt-controller;
   reg = <0x0 0x1410000 0x0 0x10000 0x0 0x1420000 0x0 0x20000 0x0 0x1440000 0x0 0x20000 0x0 0x1460000 0x0    0x20000>;
   interrupts = <0x1 0x9 0xf08>;
   linux,phandle = <0x1>;
   phandle = <0x1>;
};

- note my dtb that boots on primary only has no OPTEE firmware

So I'm thinking one of the following could be the problem:

1. the RGW board is missing the OPTEE firmware or PPA firmware (I haven't loaded any because I found no instructions for loading it to NAND on the RGW board). With no secure boot firmware, only CPU (needed for boot) comes up.

2. the reg values for interrupt-controller are incorrect in the first case, giving "GIC CPU mask not found - kernel will fail to boot" error

3. I couldn't get booting from SD card to work on my RGW board, so I am booting from NAND with the following u-boot:

sdboot=setenv bootargs root=/dev/mmcblk0p3 rw rootdelay=5 console=ttyS0,115200 earlycon=uart8250,mmio,0x21c0500;mmcinfo;ext2load mmc 0:2 $loadaddr Image; ext2load mmc 0:2 a0000000 fsl-ls1043a-rdb.dtb; booti $loadaddr - a0000000

If the MMC image has e.g. OPTEE or PPA firmware present, I must be ignoring it as I only fetch kernel and dtb from MMC.

Change u-boot on your LS1043ARDB board. Similar behavior happens if u-boot from previous version is used.

Have a great day,

I have LS1043A RGW (residential gateway) board and it has the newest u-boot image from the ASK loadable binaries, so I can't load the newer RDB u-boot onto it.

I am trying to load a Ubuntu image I made with LSDK and a DTB I hand-edited. Everything is working except I have no secondary CPUs coming up.

Re: LS1043A-RGW secondary CPUs fail to come online

andrewbarrow — Wed, 28 Mar 2018 22:15:09 GMT

Also is there a pre-compiled u-boot-sdboot.bin somewhere for the LS1043A-RGW (residential gateway)?

We did - we got a LS1043ARDB board and moved away from the ARGW board. Thanks.
