Hi there, I managed to compile and flash the W806 kit successfully using the guides provided.

However, I'm not sure which app it uploads to the board. It said "W806.bin" in the "make flash" output - but I couldn't locate that sample app that is associated with the W806.bin. Is it in the "demo" folder, or one of the apps in the "app" folder?

Also, it could be easy if there's an empty project template which I can work on different things. Is it possible to just reuse that whole "WM-SDK-W806" folder and add my custom app inside (possibly passing a parameter to the make command?), or I have to create another separate copy of "WM-SDK-W806" if I need to have my own app inside?

PS: I have read through your closed issue for libc_port.c. And I can not see the final conclusion and solution for that. So I re-open the issue.

I following the instruction on your CSDN page, with only exepctions, that I downloaded the toolchain from the WM website.

I repeated my procedure three times on:

• Alicloud ECS with Ubuntu 16.04 x86_64 (amd64)
• Ubuntu Kylin 20.04 x86_64 (amd64)
• WSL1 Ubuntu 18.04 x86_64

I tried to build wm-sdk-w806/wm-sdk-w80x. The strange things are:

• AliCloud Ubuntu, w806 [Y]/w80x [Y]
• Kylin Ubuntu, w806 [N]/w80x [Y]
• WSL1 Ubuntu, w806 [N]/w80x [Y]

I installed csky-elfabiv2-tools-x86_64-minilibc-20210423.tar.gz toolchain and cloned the source from Github into a Ubuntu in ECS. I can make all successfully and it also works fine for wm-sdk-w80x.

However when I repeat the procedure on Kylin Ubuntu 20.04 64bit version in my desktop, I got a compilation error as following:

$ make all

But building for wm-sdk-w80x works fine. I compared the sources between ECS/Desktop, the csky tools are identical, the sources are identical. But only building for wm-sdk-w806 will throw such error in my desktop. And it will throw the error in some other local machines. I git pull the source, I changed the source...... I didn't get any clue. So far I have to build the source in the ECS anyway.

The good news is that I have both working and non-working samples at hand. The bad news is that I can not find the clue.

Hello, Friends. I tried to connect the fatfs library to the SDHC card via SPI on the w806. My card initialization is going well. And when I try to read one block, I get an error on UART monitor:
CPU Exception : 7r0: 00000000 r1: 001010a9 r2: 00000001 r3: 001000a9 r4: c08ed88e r5: 7c00befb r6: b90600bf r7: a4f30200 r8: 4de428b3 r9: 4c83600a r10: 4e46aa12 r11: 3384e604 r12: ffffffff r13: 0000002d r14: 20001100 r15: 000621ea epsr: e0000340epc : 4dfa.
My question is: what could be the problem? In which files is CPU exceptions processing located? In which file is the stack fnd heap size specified?
I also tried to write a library to work with HARD I2C. Did you also fail to get the START command on the bus? Is it a hardware problem in the chip?
I will be very grateful for answers to my questions. I would really like to understand the work of this MCU in more detail.

Is there a flash tool available for macOS?

Compiled Timer Demo (/demo/tim) and flashed it to w806.

In serial monitor it doesn't serial print anything, it displays only "enter main" and then nothing...

I found some URL where you can download the toolchains and documentation without an account (and that work, unlike ipfs.io that currently times out) in a AUR package: https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=csky-toolchain-bin

Hello there,
I have just compiled a simple C++14 app with a number of constexpr and static declarations. However, it could not compile with reasons of undefined reference to __cxa_guard_acquire in the compilation.

From the static compilation guides in C++, it is noticed that some form of stdlib needed to be enabled to be successfully compiled, or disabling the thread safety mechanism. However, since this app will be also used with a FreeRTOS, I will have to use the libc ("Enable Use Lib"?) provided.

After enabling the "Enable Use Lib" in menuconfig, and compiling it, I got a warning:

0/../../../../csky-elfabiv2/bin/ld.exe: warning: cannot find entry symbol Reset_Handler; defaulting to 08010400
OBJCOPY  W806.bin
generate normal image completed.

compress binary completed.

and I could not get the program to run, and I'm suspecting it's just waiting for the user to upload binary in the terminal:
MMMCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC
It is possible too that it's not jumping to the intended program location.

first of all thank you for the answer and the project ...

well .... I bought the product from aliexpress and programmed the gpio example to see if it loaded ... now I have made a program for a greenhouse control and what is my surprise that when I save it (without compilation errors) I get it says that it is recorded (without errors) but instead there is still the led program, since my program does not use leds

按了reset没反应，怎么回事

I'm working on a small W806 app (https://github.com/nyh-workshop/w806-i2s) and trying to put a FreeRTOS inside.

From the readme, I need to comment out the "CONFIG_KERNEL_NONE = 1" or else it won't work.

However when I comment out this setting, most of the interrupts are not being called anymore, even the DMA ones.

There is someone also discussing about this here: http://ask.winnermicro.com/question/269.html. There is a possible answer at the bottom of that thread - however my Mandarin is limited and the translation seems to be not working good today.

It could mean to remove the macros, but I'm not sure which one to remove on these files.

W806 MCU, 固件大小约200KB，试图去写入位于0xF8000的Flash，运行正常，也能读取，但是重启后就进入刷机模式了。

Hello, thank you for the repo, I have a problem, it keeps showing
"please manually reset the device.
.......................................................
serial sync timeout."

even after I click on Reset, the programming doesn't start. any idea ? I'm using wm801 board V1.1.

N;B: when I use the code with arduino IDE, I can program it without pressing on RST, and works smoothly. here is the link to Arduino IDE variant : https://github.com/Hi-LinkDuino/w80x_arduino
So I mean there is no physical problem with the board.

Thank you.

Hi.
I cannot delete the input in the following cases.

I am trying to enable firmware signature but it just doesn't work.

I first enabled image key select with/without signature. the code just works irrespective of anything.

I dont see any way to flash the otp or something to load the priv key inside.

Hi there,
I am trying to write a simple I2S and DMA example of a circular buffer with only the DMA TX.
However, I could not get these "Half Complete" and "Complete" interrupts to be triggered. There is no response after calling HAL_I2S_Transmit_DMA. All it does now is to jump to the while loop in the main.

In the library, there are two DMA transfer modes: Link and Normal. I am not entirely sure what are the differences between that, so I picked the Normal.

Here are the parts of the code, which I modified from the i2s example:

main.c

int main(void)
{
    SystemClock_Config(CPU_CLK_160M);
    printf("enter main\r\n");
    
    HAL_Init();
    DMA_Init();
    I2S_Init();
    
    // I2S_BUFFER_SIZE is 512 in my modified example:
    memset(tx_buf, 0x00, I2S_BUFFER_SIZE);

    HAL_I2S_Transmit_DMA(&hi2s, (uint32_t*)tx_buf, I2S_BUFFER_SIZE);

    while (1)
    {
        printf(".");
        HAL_Delay(1000);
    }
}

static void DMA_Init(void)
{
    __HAL_RCC_DMA_CLK_ENABLE();
    
    HAL_NVIC_SetPriority(DMA_Channel0_IRQn, 0);
    HAL_NVIC_EnableIRQ(DMA_Channel0_IRQn);
    
}

void HAL_I2S_TxHalfCpltCallback(I2S_HandleTypeDef *hi2s)
{
    printf("tx halfcplt\r\n");
}

void HAL_I2S_TxCpltCallback(I2S_HandleTypeDef *hi2s)
{
    printf("tx cplt\r\n");
}

wm_hal_msp.c:

void HAL_I2S_MspInit(I2S_HandleTypeDef *hi2s)
{
    if (hi2s->Instance == I2S)
    {
        __HAL_RCC_I2S_CLK_ENABLE();
        __HAL_RCC_GPIO_CLK_ENABLE();
        
        __HAL_AFIO_REMAP_I2S_MCK(GPIOA, GPIO_PIN_7);
        __HAL_AFIO_REMAP_I2S_WS(GPIOB, GPIO_PIN_9);
        __HAL_AFIO_REMAP_I2S_CK(GPIOB, GPIO_PIN_8);
        __HAL_AFIO_REMAP_I2S_MOSI(GPIOB, GPIO_PIN_11);
        __HAL_AFIO_REMAP_I2S_MISO(GPIOB, GPIO_PIN_10);
        
        hdma_i2s_tx.Instance = DMA_Channel0;
        hdma_i2s_tx.Init.Direction = DMA_MEMORY_TO_PERIPH;
        hdma_i2s_tx.Init.DestInc = DMA_DINC_DISABLE;
        hdma_i2s_tx.Init.SrcInc = DMA_SINC_CIRCULAR;
        hdma_i2s_tx.Init.DataAlignment = DMA_DATAALIGN_WORD;
        hdma_i2s_tx.Init.Mode = DMA_MODE_NORMAL_CIRCULAR;
        hdma_i2s_tx.Init.RequestSourceSel = DMA_REQUEST_SOURCE_I2S_TX;
        
        hdma_i2s_tx.LinkDesc = tx_desc;
        
        if (HAL_DMA_Init(&hdma_i2s_tx) != HAL_OK)
        {
            Error_Handler();
        }
        __HAL_LINKDMA(hi2s, hdmatx, hdma_i2s_tx);   

        HAL_NVIC_SetPriority(I2S_IRQn, 1);
        HAL_NVIC_EnableIRQ(I2S_IRQn);
    }
}

Is the Circular mode, when running, should trigger both the Half-Transfer Complete and Transfer Complete interrupts continuously?
