Hello Infineon Community,

I have th CYHVMS-64K-56-001 Evaluation Kit and am looking to get started with it. However, I'm having difficulty finding comprehensive documentation or any related resources for this specific kit.

Could anyone please provide or direct me to:

1. A detailed user manual or getting started guide for the CYHVMS-64K-56-001 Evaluation Kit.
2. Any example code or projects that utilize this kit.
3. Relevant software tools or libraries that are compatible with this evaluation kit.

I could find it on the project-creator of modulus toolbox either. 

Thank you in advance for your help.

Hi community，

PSoC Creator 里面似乎只支持头文件直接放在.cydsn 文件夹下面，如果在 .cydsn 文件夹下面再新建文件夹似乎就找不到路径了，请问一下可以添加路径吗？我没有找到可以修改的地方

谢谢

Hi community，

我在 modustoolbox 里面使用 PSoC4100S MAX 系列的 Demo 板，下载的示例程序，编译的 PDL 文件 cy_gpio.h头文件有 error，虽然有 error 但是还是能够编译成功以及烧录，如下图所示，请问一下怎么解决，谢谢！！！

Dear Sirs and Madams,

We are using PSoC4S MAX to explore configuring a proximity sensor.

Is it better to place a mesh ground or an active shield around the proximity sensor if I want to increase the detection distance of the proximity sensor?

Although the active shield seems to extend the detection distance more than the mesh ground experimentally, the noise level is higher with the active shield than the mesh ground.

That leads to a drop in SNR.

Regards,

Hello

I'm using CY8C4745FNI-S412.

I want to trim IMO using WCO.

But there is no option for trim IMO.

How can I trim IMO using WCO?

Hi,

I’m using the CY8CKIT-148 (PSoC CY8C4147AZI-S475) and I’m trying to get FW update working without using the DFU library.  I’m mimicking how the mtb-example-psoc4-dfu-basic sample (here: https://github.com/Infineon/mtb-example-psoc4-dfu-basic) which works. The only difference is I’m not using the DFU protocol.  Downloading the app works, I’m using a SHA256 hash to verify image written to flash.  However, when I reset the system after setting the app number in ram common, the app doesn’t start the bootloader starts.

A couple of questions: 

1) How does the processor know where APP 1 begins in flash?  I know there’s DFU meta data at the end of flash (0x0001FA00) which does contain this information, but does the processor use this information? 

2) When using the Device Firmware Update Host Tool 2.0 to load a .cyacd2 file, the app starting address and len is identified by @APP_INFO line.  I’m assuming this is written to the flash meta data.  Is this correct? 

Thanks,

Dean

Hi,  community

I was looking at the datasheet and was wondering why the current flowing in Deepl sleep mode for PSoC4000S is 2.5µA(typ) and max 60µA?
Since most of the peripherals are stopped in Deep sleep mode, I figured that the inherent design effects are almost negligible.
What is the reason or idea behind the data variation?

Working with a PSOC4 dev board (CY8KIT-149), trying to get SHA256 and CRC crypto functions working.  Both functions constantly return 0.  Cy_Crypto_Enable(CRYPTO) is successful, all of the other functions return success, but the SHA256 is zero, which isn't correct.   Here's the snippet of code I'm using:

void update(uint8_t *hash)
{
    cy_en_crypto_status_t cy_status;

    uint32_t *app_flash = (uint32_t*)CY_DFU_APP1_VERIFY_START;
    CY_ALIGN(4) uint32_t buffer[CY_FLASH_SIZEOF_ROW / sizeof(uint32_t)] = {0};
    CY_ALIGN(4) uint8_t image_hash[CY_CRYPTO_SHA256_DIGEST_SIZE];
    uint32_t flash_offset;



    /// init sha256 object
    cy_status = Cy_Crypto_Sha_Init(CRYPTO,
                                   CY_CRYPTO_MODE_SHA256,  /* Hash mode */
                                   &ctx);

    if (cy_status != CY_CRYPTO_SUCCESS)
    {
        GK_LOG_ERROR("SHA init failed, status: %lu", cy_status);
        return GK_STATUS_CRYPTO_FAILED;
    }


    // Start at beginning of app flash area calc sha256 hash
    flash_offset = CY_DFU_APP1_VERIFY_START;
    while (flash_offset < _curr_offset)
    {
        // read in a row of data
        for(uint32_t i = 0; i < (CY_FLASH_SIZEOF_ROW / sizeof(uint32_t)); i++)
        {
           buffer[i] = *app_flash;
           app_flash++;
        }

        flash_offset += CY_FLASH_SIZEOF_ROW;

        // hash chunk
        cy_status = Cy_Crypto_Sha_Partial(CRYPTO, (uint8_t const *)buffer, sizeof(buffer), &ctx);

        if (cy_status != CY_CRYPTO_SUCCESS)
        {
           GK_LOG_ERROR("Failed to hash update, status: %lu", cy_status);
           return GK_STATUS_CRYPTO_FAILED;
        }
    }

	=============> Always returns zero ================
    cy_status = Cy_Crypto_Sha_Finish(CRYPTO, image_hash, &ctx);
    if (cy_status != CY_CRYPTO_SUCCESS)
    {
        GK_LOG_ERROR("Failed to finish hash, status: %lu", cy_status);
        return GK_STATUS_CRYPTO_FAILED;
    }

    cy_status = Cy_Crypto_Sha_Free(CRYPTO, &ctx);

    return GK_STATUS_SUCCESS;
}

We are using the PSoC 4.2 BLE chipset and have issues with disconnection.

I suspect that the algorithm for detecting and avoiding strong blockers /poor channels is not working or not active.

CyBle_GapGetChannelMap() always returns that all channels are active and i can also measure that there is activity on all channels even though there are strong WIFI disturbance.

Comparison testing with other BLE devices connected to an IPhone show that BLE skips the channels with high disturbance. 

1. How is the Channel map updated by the BLE Stack? do i need to trigger the learning and update in the code or enable it somewhere?

2. If it is supposed to be handled by our own algorithm and by using  CyBle_GapcSetHostChannelClassification(), how do i get the information of the active channel and coresponding rssi level etc?
