TDA4VM: R5F Lockstep using u-boot

Adam Kubiak

Part Number: TDA4VM

Hi,

I have a few questions regarding the lockstep for R5F using u-boot.

I am using the 06_02 SDK version.

In the k3-j721e-mcu-wakeup.dtsi file the lockstep for MCU R5F is enabled, but the R5F boots without the lockstep.
I attached the screenshot from the CCS debugger with the CTRLMMR_MCUSEC_CLSTR0_CFG register settings.

According to the data from the register the CPU lockstep bahaviour is disabled and the LOCKSTEP is turned off.

How can we enable the lockstep for the MCU R5F cores using u-boot?

How can we enable the lockstep for the MAIN R5F cores using u-boot? Does enabling the lockstep in k3-j721e-main.dtsi file is enough to enable the lockstep?

Hi Adam,

I believe you are loading the mcu r5f firmware at the R5 SPL level. Then in that case the default efuse values are used.
That can be either in split mode or lockstep based on the samples.

Now if you load the firmware and boot the r5fs in u-boot or linux then the DT property takes effect and you
can boot any of the r5fss in either lockstep-mode or split-mode based on the DT property.

So if you want to start/load any of the r5fs in the lockstep-mode advice you to load the firmware and start them from u-boot
instead of R5 SPL.

Regards,
Keerthy

Hi,

We are loading the R5F firmware using the remoteproc. The firmware is stored on sd card in rootfs/lib/firmware.

Regards,

Adam

Hi Adam,

Could you please share the entire boot log so that i can investigate what exactly is happening.

Hi,

I will provide you the log as soon as I can.

I have a question is the way we are booting the R5F cores the one that uses the configuration from the device tree?

Hi,

I attached the log from u-boot.

I will also repeat my question.

Is the way we are booting the R5F cores the one that uses the configuration from the device tree?

0 Keerthy J over 4 years ago in reply to Adam Kubiak

Hi Adam,

R5 SPL is doing 2 things:

1) Loads main_r5fss0_core0 firmware and starts it in split mode as the DT has lockstep-mode = <0> in arch/arm/dts/k3-j721e-main.dtsi.
Hence you see the message in your boot log:
Remoteproc 2 started successfully.

Remoteproc 2 for r5 is the main_r5fss0_core0 if you see the arch/arm/dts/k3-j721e-r5-common-proc-board.dts:

aliases {
remoteproc0 = &sysctrler;
remoteproc1 = &a72_0;
remoteproc2 = &main_r5fss0_core0;
remoteproc3 = &main_r5fss0_core1;
};

So main_r5fss0 is booted in split mode as per the DT configuration.

Please check:
http://www.ti.com/lit/pdf/spruil1

CTRLMMR_SEC_CLSTR0_CFG Register Address: 0x45A40040

bit 3: lockstep_en if its set then lockstep mode is supported on the device.

You could try to change arch/arm/dts/k3-j721e-main.dtsi:

main_r5fss0: r5fss@5c00000 {
compatible = "ti,j721e-r5fss";
lockstep-mode = <0>;

main_r5fss0: r5fss@5c00000 {
compatible = "ti,j721e-r5fss";
lockstep-mode = <1>;

And try to get main_r5fss in lockstep-mode subjected to LOCKSTEP_EN bit set.

2) Once SPL is done with its tasks it is jumping to a firmware:

jump_to_image_no_args function in arch/arm/mach-k3/common.c.

This does not take any DT property as the mcu r5 itself is executing the SPL and hence for
this we do not read the DT property. So i believe by default on your samples mcu_r5f is in split mode.

Look at the description of Table 5-660. CTRLMMR_MCUSEC_CLSTR0_CFG Register Field Descriptions:

in: www.ti.com/.../spruil1

Bit 3: LOCKSTEP_EN is 0 on your sample which implies:

Lockstep enable. Indicates if R5 lockstep operation is supported on
the device

Your register reads 0x0 which means lock step not supported.

So MCU_r5ss in lockstep mode is not supported on your sample.

Hope this clarifies the behavior on your board.

Best Regards,
Keerthy

Hi Keerthy,

Thank you for that analysis.

I checked the CTRLMMR_SEC_CLSTR0_CFG Register and the lockstep for the MAIN R5F is also not enabled.

I'm attaching the screenshot:

Does this mean that even if i enable the lockstep for MAIN R5F in arch/arm/dts/k3-j721e-main.dtsi it won't work?

Or if i enable the lockstep in the device tree the MAIN R5F should boot in a lockstep mode?

Kind regards,

Adam

TI__Guru**** 150970 points

Hi Adam,

As replied earlier only of the LOCKSTEP_EN is enabled on your device it can be supported.

lockstep_en = !!(stat & PROC_BOOT_STATUS_FLAG_R5_LOCKSTEP_PERMITTED);
if (!lockstep_en && cluster->mode) {
dev_err(cluster->dev, "lockstep mode not permitted, force configuring for split-mode\n");
cluster->mode = 0;
}

The above code in Linux clearly checks that and supports only split-mode if lockstep_en is not set.

So for your case this will not be supported.

Hope you can resolve the issue with information provided.

Best Regards,
Keerthy

Hi Keerthy,

Thanks for the help.

I have one last question.

Is there any way I can enable the lockstep or is it disabled on a hardware level? And if yes how can i do that?

We are using the evaluation board but we also have our custom hardware with TDA4.

0 Keerthy J over 4 years ago in reply to Adam Kubiak

TI__Guru**** 150970 points

Hi Adam,

I consulted the expert in R5F domain. The lockstep-mode_en bit tells that it is not supported on your device.
Lockstep mode cannot be supported on your device i confirm. Please resolve the issue.

Best Regards,
Keerthy

Hi Adam,

Just a point on reading CTRLMMR_SEC_CLSTR0_CFG registers.

Try reading the registers from M3, instead of R5.
The access to these registers from other cores may have been blocked in latest release.
