hi，大家好

目前在使用Psoc6 ble开发板开发，M0核和M4核都有使用，分别建立了工程，在各自的核擦写都是成功的。现在遇到的问题是用M0核做boot loader，跳转到M4核执行App后，擦写就会失败 。请帮忙看看，谢谢谢谢！

I'm using CYTVII-C-2D-6M-327-SET evaluation kit for my project.   I require information's about pinout details exposed out in dev kit and its schematic diagram .

I couldn't get those documents.  could you support on this ?

Thanks.

Hello Community,
I faced below error while I was using OneEye tool for debugging. pls looked into it.

after self-programming and reset, the software blocked at function _c_init_entry (judged by asm code) the trap position is where the global variable are being initialized by data stored in flash the flash area (32 bytes) have ecc errors why and how did these ecc errors occur? Show Less

hi, while building the project am getting following error.
make[1]: *** [../mtb_shared/core-make/release-v3.0.3/make/core/build.mk:435: C:/DemoProject/build/CY8C6245LQI/Release/AIController-Psoc6.elf] Error 1
make: *** [../mtb_shared/core-make/release-v3.0.3/make/core/main.mk:376: secondstage_build] Error 2

I tried reinstalling the Modustoolbox, also corrected the path of Environment variable, but nothing seems to be working.

Hi, I tried to implement the mtb-littlefs in my xmc7100D board  with few modification to mq serial-read/write program: But I am encountering an error: could you tell me why I am unable to do "

"

My COM Port:

in my lfs.c:

 

lfs_ssize_t lfs_file_read(lfs_t *lfs, lfs_file_t *file,
        void *buffer, lfs_size_t size) {
    int err = LFS_LOCK(lfs->cfg);
    if (err) {
        return err;
    }
    LFS_TRACE("lfs_file_read(%p, %p, %p, %"PRIu32")",
            (void*)lfs, (void*)file, buffer, size);
    printf("lfs_file_read(%p, %p, %p, %"PRIu32")",
                (void*)lfs, (void*)file, buffer, size);
    LFS_ASSERT(lfs_mlist_isopen(lfs->mlist, (struct lfs_mlist*)file));

    lfs_ssize_t res = lfs_file_rawread(lfs, file, buffer, size);

    LFS_TRACE("lfs_file_read -> %"PRId32, res);
    LFS_UNLOCK(lfs->cfg);
    return res;
}

 

How do I solve the LS_ASSERT function from failing?

Also how do I verify little_fs is not mounted on the internal flash but on the inbuild external flash memory.

Best,

PrasadA

My purpose is to control the private server motor. Because most servo motors are controlled using pulses. So if it involves the acceleration and deceleration of the motor, the interval between each pulse may be different. Therefore, every time the timer is interrupted, the entry time of the next timer will be changed. In STM32, I can make the time into a list. Then directly import the register TIM3->ARR = tim[X]. However, it was found that in XMC1302, it is not allowed to write values directly to the register. But need to use

TIMER_Stop(&TIMER_0);
status = TIMER_SetTimeInterval(&TIMER_0, tim[ X ]);
if (status == TIMER_STATUS_SUCCESS)
{
        TIMER_Start(&TIMER_0);
}

This is how you can reset it. But this code runs too slowly. About 60US. This is obviously too long. Is there a faster way?

您好，我在使用xmc4800，ethercat。这个示例代码ETHCAT_SSC_AUT_BASE_XMC48里添加PMSM_FOC组件，报了两个错误，我在单独使用PMSM_FOC这个工程正常编译运行。但在ETHCAT_SSC_AUT_BASE_XMC48就会出现这两个问题，请看附件图

多次尝试无法解决，请帮看一下。感谢！！！
