core: recursive dependency init and runtime Camera/Ethernet clock setup by dani-clo · Pull Request #499 · arduino/ArduinoCore-zephyr

dani-clo · 2026-05-27T10:11:43Z

This improves the current deferred-init initialization process.

Add recursive initialization of required device dependencies before initializing the target deferred-init device itself.
Complete the runtime bring-up for Camera and Ethernet, including deferred pwm-clock initialization, replacing the previous behavior where the external clock was always enabled even when Camera/Ethernet were not in use.

Looks like a proper fix. Closed out the earlier attempt at trying to defer camera startup, which worked up until the defer init of I2C and PWM...

Thanks

KurtE · 2026-05-27T20:56:41Z

Update: I tried this on GIGA R1 and it appeared to work, at least for first image...
Trying now on Portenta H7.

So far: I believe I need to enable the GC2145 camera in the config in the same way it is on GIGA:

My app to display on ST7796 is not retrieving images yet...
First trying to remember where USART6 is on the MID carrier, to see any debug messages. ..

But at least it looks like the clock is starting and the like:

On GIGA, I was able to get the camera to read more reliably, by using some of the recovery code that was added to zephyr maybe 7 months ago:
zephyrproject-rtos/zephyr@eb7e332
In particular, in the video_stm32_dcmic file

#if 1
static void stm32_dcmi_process_dma_error(DCMI_HandleTypeDef *hdcmi)
{
	struct video_stm32_dcmi_data *dev_data =
		CONTAINER_OF(hdcmi, struct video_stm32_dcmi_data, hdcmi);

	LOG_DBG("Restart DMA after Error!");

	/* Lets try to recover by stopping and restart */
	if (HAL_DCMI_Stop(&dev_data->hdcmi) != HAL_OK) {
		LOG_WRN("HAL_DCMI_Stop FAILED!");
		return;
	}

	if (HAL_DCMI_Start_DMA(&dev_data->hdcmi,
			       DCMI_MODE_CONTINUOUS,
			       (uint32_t)dev_data->vbuf->buffer,
			       dev_data->vbuf->size / 4) != HAL_OK) {
		LOG_WRN("HAL_DCMI_Start_DMA FAILED!");
		return;
	}
}

void HAL_DCMI_ErrorCallback(DCMI_HandleTypeDef *hdcmi)
{
	stm32_dcmi_process_dma_error(hdcmi);
}

#else
void HAL_DCMI_ErrorCallback(DCMI_HandleTypeDef *hdcmi)
{
	LOG_WRN("%s", __func__);
}
#endif

Without this on GIGA, I got maybe one frame before it errored and hung. With this it has been running for a while now.

Update: I tried this on GIGA R1 and it appeared to work, at least for first image...

@KurtE
Finally updated with pr 499 and gave it a try with what seems to work before the defer init stuff. Right now display works but getting no frames displayed at all. See in debug window

Update: PortentaH7. in the overlay file, I see that
arduino_portenta_h7_stm32h747xx_m7.overlay

	dmas = <&dma1 0 75 (STM32_DMA_PERIPH_TO_MEMORY | STM32_DMA_PERIPH_NO_INC |

			    STM32_DMA_PRIORITY_HIGH) STM32_DMA_FIFO_1_4>; //FULL for 7670, default FIFO_1_4

Changed it from FULL to match GIGA...
Still not getting through, wonder what else is different between GIGA/Portenta H7. Obviously the pins its on

Also wondering about about dmas setting for both. On current source a while ago I had to change

	dmas = <&dma1 1 75 (STM32_DMA_PERIPH_TO_MEMORY | STM32_DMA_PERIPH_NO_INC |
			    STM32_DMA_MEM_INC | STM32_DMA_PERIPH_32BITS | STM32_DMA_MEM_32BITS |
			    STM32_DMA_PRIORITY_HIGH) STM32_DMA_FIFO_FULL>; //FULL for 7670, default FIFO_1_4

As something changed to make it 1 based instead of 0...
Did not help ...

Portenta H7: I tried saveral different things and they all failed to do DMA from camera to SDRAM... The fix I mentioned for the zephyr side DCMI works on GIGA, although you still get a reasonable number of DMA errors. I think there may have been another PR later on Zephyr that may have helped earlier.

But for a quick and dirty I setup the 0th buffer to use memory returned by Malloc and that works... Quick and dirty sketch from camera to ST7796...

Sorry not a great picture, but...

@dani-clo do you want this level of information here under the PR? Or should I create a PR to for example update the PortentaH7 overlay/config and another against arduino/zephyr to bring in some of the DCMI stuff?

Some of the apps I have been testing things out here are up on my github project: https://github.com/KurtE/Arduino_GIGA-stuff
Most under zephyr or zephyr display....

Sketch to output GIGA to display shield: Zephyr_GigaCameraDisplay_GFX
Sketch to output to ST7796: camera_to_st77xx
sketch to output over USB: camera_to_USB_two_ways. Does the RAW like example sketch, plus BMP format for
Ardum_Mini_ContinuousShots... app (Not sure if Linux version exists)

dani-clo · 2026-05-29T10:00:26Z

Thanks for the detailed investigation and testing @KurtE !

So, to summarize where we are:

deferred-init and runtime clock/peripheral initialization now seem to be working correctly;
the remaining issues appear to be in a separate area: DCMI behavior, DMA recovery, camera buffer allocation.

I think these topics are now somewhat independent from the deferred-init/clock scope of this PR.

Could you please open separate issues/PRs/discussions for the remaining camera/DMA topics?

I’d prefer to keep this PR focused on the deferred-init/clock changes so we can hopefully review and close it in the next few days.

@KurtE

Finally updated with pr 499 and gave it a try with what seems to work before the defer init stuff. Right now display works but getting no frames displayed at all. See in debug window

Redid the PR incorporation and tried again. Still not getting anything but now I am also seeing this error:

Unable to set display format

Which is rather strange.

EDIT:
My fault - got it working forgot to update something. Now getting images:

Avg display Time: 55238 fps:18.10

I agree, except maybe on this one, you might update the Portenta H7 camera overlay and conf file.

Need new PR(s), probably in Arduino/Zephyr, to bring in some of the updates to DCMI and maybe GC2145 code to
actually get it to work at all with DMA.

a) The recovery code I added in to DMA error.
b) @mjs513 If I remember correctly Alan Vol... also later added a fix to improve DMA? Will try figure out where...

KurtE · 2026-05-29T17:14:02Z

@dani-clo @pillo79 @pennam Quick question on this:

Is Arduino planning to zephyr 4.4 soon? I see there is now an active branch up on Arduino where some PRs have PRs are pending... Should we be testing against that version.

EDIT: I tried by editing west.yaml to use the 4.4... west update downloaded it, but builds fail...

kurte@KurtXPS8950:~/git/ArduinoCore-zephyr$ ./extra/build.sh giga

Build target: arduino_giga_r1//m7 --shield arduino_giga_display_shield
Failed to get variant name from 'arduino_giga_r1//m7'

Guessing I would need the Monza branch of ArduinoCore-zephyr to go that route.

KurtE · 2026-05-31T13:05:59Z

I did create a PR:
https://github.com/arduino/zephyr/pull/20/changes
For the 4.2 branch which has some of the DMA recovery stuff. It was cherry picked from the
zephyr sources with the hashtag of the commit.

But if switching soon to 4.4 release of zephyr, than probably should figure out how to get the
builds to work on it... As I see @pennam linked to this with 4.4 comment...
But so far the couple attempts with Monza branch and using the 4.4 branch of zephyr, the commands like
./extra/build.sh giga
fail as mentioned above

facchinm · 2026-06-01T07:57:56Z

Hi Kurt,
the plan is to switch to 4.4 soon enough, as you've seen the monza branch is being used as integration; the biggest changes are on MBEDTLS and deferred-init; right now we only ported potentah7 but once that's validated we can use the same approach for the other failing targets. We'll keep you posted as soon as the CI is green 🙂

mjs513 · 2026-06-01T12:22:26Z

Portenta H7: I tried saveral different things and they all failed to do DMA from camera to SDRAM... The fix I mentioned for the zephyr side DCMI works on GIGA, although you still get a reasonable number of DMA errors. I think there may have been another PR later on Zephyr that may have helped earlier.

@KurtE
I decided to give this a try and used the camera lib that moded a very long time ago that where we used fixed buffers as opposed to the malloc. We did this to improve frame rates on the giga. After some playing to make sure st7796 worked I gave it a try and worked no issues.

As you said with using the fixed buffer (or your malloc mod) I got no images displayed or received from the camera.

Just thought I would give an update
