is using of arm toolchain from developer.arm.com feasible?

MaxMn
 

After installing zephyr-sdk-0.11.2, I checked arm g++ version:
arm-zephyr-eabi-g++ (crosstool-NG 1.24.0.37-3f461da-dirty) 9.2.0
Why "dirty"? Should I worry?

How feasible is it to use the a toolchain direct from developer.arm.com (1) when buliding zephyr projects?

More general, why vendors tend to supply their own toolchain builds? (My target is STM32. ST goes way "further" and supplies with their STM32CubeIDE old GNU Tools for STM32 7-2018-q2-update.20190328-1800 7.3.1 20180622 (release) [ARM/embedded-7-branch revision 261907])

Re: unable to build #west

Bolivar, Marti
 

You appear to be using Python 3.5. Zephyr requires Python 3.6.

I am surprised the build got this far along. You should have seen an
error about this earlier.

Re: Enable traces on Serial Wire Output #debugging

And I forgot to include the FreeRTOS part:

#define configCPU_CLOCK_HZ                      ( SystemCoreClock )
#define configTICK_RATE_HZ                      ( 1000 )

Where SystemCoreClock is set to 16000000 by default.

Hi there,

Thanks for the feedback and sorry for the delay. Here is my function that initializes the clock, it is called right after HAL_Init():

    // Configure the main internal regulator output voltage
    __IO uint32_t tmpreg;
    SET_BIT(RCC->APB1ENR, RCC_APB1ENR_PWREN);

    // Delay after an RCC peripheral clock enabling
    tmpreg = READ_BIT(RCC->APB1ENR, RCC_APB1ENR_PWREN);
    tmpreg = tmpreg;

    MODIFY_REG(PWR->CR1, PWR_CR1_VOS, (PWR_REGULATOR_VOLTAGE_SCALE3));

    // Delay after an RCC peripheral clock enabling
    tmpreg = READ_BIT(PWR->CR1, PWR_CR1_VOS);
    tmpreg = tmpreg;

    // Initializes the CPU, AHB and APB busses clocks
    RCC_OscInitTypeDef RCC_OscInitStruct = {0};
    RCC_OscInitStruct.OscillatorType      = RCC_OSCILLATORTYPE_HSI | RCC_OSCILLATORTYPE_HSE;
    RCC_OscInitStruct.HSEState            = RCC_HSE_ON;
    RCC_OscInitStruct.HSIState            = RCC_HSI_ON;
    RCC_OscInitStruct.HSICalibrationValue = 16;
    RCC_OscInitStruct.PLL.PLLState        = RCC_PLL_ON;

    RCC_OscInitStruct.PLL.PLLN            = 144;
    RCC_OscInitStruct.PLL.PLLP            = RCC_PLLP_DIV2;
    RCC_OscInitStruct.PLL.PLLQ            = 6;
    HAL_StatusTypeDef hal_ret = HAL_RCC_OscConfig(&RCC_OscInitStruct);
    if (hal_ret != HAL_OK)
    {
        return -ENOTSUP;
    }

    // Initializes the CPU, AHB and APB busses clocks
    RCC_ClkInitTypeDef RCC_ClkInitStruct = {0};
    RCC_ClkInitStruct.ClockType      = RCC_CLOCKTYPE_HCLK | RCC_CLOCKTYPE_SYSCLK | RCC_CLOCKTYPE_PCLK1 | RCC_CLOCKTYPE_PCLK2;
    RCC_ClkInitStruct.SYSCLKSource   = RCC_SYSCLKSOURCE_PLLCLK;
    RCC_ClkInitStruct.AHBCLKDivider  = RCC_SYSCLK_DIV1;
    RCC_ClkInitStruct.APB1CLKDivider = RCC_HCLK_DIV4;
    RCC_ClkInitStruct.APB2CLKDivider = RCC_HCLK_DIV2;
    // HAL_RCC_ClockConfig() ultimately calls HAL_InitTick()
    hal_ret = HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_4);
    if (hal_ret != HAL_OK)
    {
        return -ENOTSUP;
    }

    // Initializes the peripherals clocks
    RCC_PeriphCLKInitTypeDef PeriphClkInitStruct = {0};
    PeriphClkInitStruct.PeriphClockSelection = RCC_PERIPHCLK_USART6 | RCC_PERIPHCLK_SDMMC1 | RCC_PERIPHCLK_CLK48;
    PeriphClkInitStruct.Usart6ClockSelection = RCC_USART6CLKSOURCE_HSI;
    PeriphClkInitStruct.Clk48ClockSelection  = RCC_CLK48SOURCE_PLL;
    PeriphClkInitStruct.Sdmmc1ClockSelection = RCC_SDMMC1CLKSOURCE_CLK48;
    hal_ret = HAL_RCCEx_PeriphCLKConfig(&PeriphClkInitStruct);
    if (hal_ret != HAL_OK)
    {
        return -ENOTSUP;
    }

    // Configure the Systick IRQ for FreeRTOS timebase
    HAL_SYSTICK_Config(HAL_RCC_GetHCLKFreq() / 1000);
    // Configure the Systick
    HAL_SYSTICK_CLKSourceConfig(SYSTICK_CLKSOURCE_HCLK);

    // SysTick_IRQn interrupt configuration done in HAL_MspInit()

    SCB_EnableICache();
    SCB_EnableDCache();

    return 0;

Also, not sure if it is related but I have 2 Time bases:

  • STM32 uses timers (TIM6) to generate interruptions for HAL
  • FreeRTOS uses SysTick for OS functions

Thanks for your help, in parallel I will look into RTT alternative.

Have you enabled CONFIG_NET_BUF=y? That’s the only dependency for CONFIG_NET_BUF_USER_DATA_SIZE being defined.

Question about the QSPI flash memory in the nrf52840 PCA10056 board #flash #nrf52840 #spi

henrique.guimaraes@...
 

Good afternoon, I'm a zephyr newbie, trying to implement it into an IoT project!

I'm aware that there is already a driver for the MX25 flash memory device in the nrf's dev kit, but I wasn't able to import it successfully to my code nor was I able to use it properly. I checked in the Menuconfig application and marked every box that had anything to do with QSPI and the NRF's flash drivers, but was still unsuccessful.

How to use the flash device driver properly? I know this is a very newbie question, but I want to do it the right way, not by brute forcing it. 

Thanks.

trying to add support for STM32F334 discovery

Daniel McBrearty <danielmcbrearty@...>
 

hello all,

I am new to Zephyr, just want to give it a try. I don't have any of the supported boards, but I have a STM32F334 Discovery which is close to several supported ones. I thought I'd see if I could add support by making a copy of STM32F3 Discovery. I also used some settings from Nucleo STM32F334R8 which seems to have a very similar chip.

I can build and flashing seems to work, but no blinking LED (the red user LED should be assigned to led0).

My build / flash output:

A few warnings but I think it is progrming the board OK - I see the interface LED flash and from the above, OCD seems to verify the code.

The only thing I wonder about is which include file to use in my dts file. At the moment I have:

I'm not sure if this the rason that I cannot seem to get blnky running on this board. Ideas? Thank you.

Hi David,

I'm not a SWO user myself but I'm suspecting a clock set up issue.
On FreeRTOS, what was the clock configuration you were using ?

Cheers

As mentioned in an earlier email (to which you replied without context so I had to start a new thread), RTT does work across reboots without problems, at least on Nordic platforms.

I do not know whether Zephyr does anything at all to the SWO pin connected to the debugger chip, and especially not on an STM32 platform (I copied Erwan who maintains these boards), but I might be wrong.

I am still struggling to figure out why I cannot keep receiving traces through reboots. On the same dev board with FreeRTOS it was consistent: I was able to log target resets without re-launching swoview.

I don't understand why even with the basics samples (blinky, button, ...) when I reset the target the SWO output is "broken" and I have to launch a new instance of swoview to get traces again. Is it something in the DTS to configure ?

Thanks

Hi all,
I use segger ozone to do debugging via RTT it's free download which may be helpful.   
It does have swo trace and STM32 JTAG configuration inbuilt it may be something to consider. 

But I work with Nordic silicon so not sure about the STM chips.

Zephyr+BLE dongle: Maping a USB port and full stack inside

Imóveis Nacionais
 

Hi
This is my first contact with Zephyr project. My question is about good or wrong direction:
I need a BLE 5 "autonomous" dongle similar to BLED112 BLE 4 one. It maps a USB PORT on the computer and 100% hides BLE stack inside (no need for BLE stack on the host computer).
I have already a nRF52840 dongle. I am aware of the Zephyr HCI_USB sample but that sample warns reader that it needs BLUEZ on the host computer (sure because it needs to "speak HCI with the dongle"). So its seems not the right sample on the one handle but the interesting one in order to change it to reach my objective.
I am asking to experienced Zephyr users and programmers about the good direction, tips...

Thanks you
Alex

Re: Enable traces on Serial Wire Output #debugging

Hi there,

 

We don’t use SWO but RTT (also from Segger) and we don’t need to reset the JLinkRTTViewer/Logger when we reset the target.

Could it be that the way Zephr flashes and then resets the target (pin reset vs software reset) is different from FreeRTOS?

 

In theory this is all handled by the on-board debugger chip so it should make no difference.

 

Which board are you using?

 

Carles

Subject: [Zephyr-devel] API meeting next week: Focusing on watchdogs

Hi all,

Next week (Tuesday 10th of March) we will focus our attention to
watchdog handling in Zephyr.

We recently closed #22858 with the merge of #22859, but this was a
temporary solution to what is ultimately a wider problem that requires
a discussion regarding the way Zephyr manages watchdogs in general.

A good description of the current issues with the
CONFIG_WDT_DISABLE_AT_BOOT option can be found in #22858.

During the call we will discuss the approach we want to take and
document it in #23282, which I just created today.

Original issue:
https://github.com/zephyrproject-rtos/zephyr/issues/22858
Pull request:
https://github.com/zephyrproject-rtos/zephyr/pull/22859
New tracking issue:
https://github.com/zephyrproject-rtos/zephyr/issues/23282

Meeting:
https://github.com/zephyrproject-rtos/zephyr/wiki/Zephyr-Committee-and
- Working-Group-Meetings#zephyr-api-discussion

Thanks,

Carles
