I am using Application Kit TC3X7 V2.0 TFT board

I have configured BMHD but  the board all the time boots from Internal flash ignoring BMHD settings

If i want to use Alternate Boot Mode or BMI  to boot , which all changes i need to do on the board?

Hi,

I am using CY8C6245LQI-S3D42 and I used the DFU examples to boot the system and created the application to run on AM4 core and everything is working well. 

I wait for 5 sec in DFU to check if there is any updates or just move with the Application code.

I find that sometimes the device stops booting once in a blue moon. Now If I flash again just the boot loader, everything is fine , I need not have to write the Application, it moves from DFU in 5 sec to application.

I believe, there is some how the flash/DFU is getting corrupted.  I want to protect this scenario. Can some one share how do I protect my DFU so that it never erases . Any example's will be appreciable, I am using USB CDC transport in DFU.

Regards,

Madhav

Hello,

I am trying to flash littlefs filesystem on the qspi external serial flash memory in XMC7100 V1.1. As I see library mtb-littlefs is not included in the XMC7100 kit but i have included the mtb-littlefs from PSoc6 Kit to my project and in makefile included target as XMC7100 (my board).

BOARD: XMC7100 EVK Lite v1.1

Memory: External QSPI flash memory

These are the errors when I try to builld the file:

When I comment the line:

    /** Continuous transfer merge timeout.
     * After this period the memory device is deselected. A later transfer, even from a
     * continuous address, starts with the overhead phases (command, address, mode, dummy cycles).
     * This configuration parameter is available for CAT1B devices. */
    //.mergeTimeout = CY_SMIF_MERGE_TIMEOUT_1_CYCLE
#endif /* CY_IP_MXSMIF_VERSION */

I get failed to creat spi device block:

Could someone help me with ".mergeTimeout = CY_SMIF_MERGE_TIMEOUT_1_CYCLE" error?

When using the mtb-littlefs through the mtb-shared, how do I enable the cy_hal, freertos and thread in make file?
I tried to add the necessary comments on my application makefile but it is not enabling the corresponding if condition in the files in mtb-shared folder/mtb-littlefs!

best regard,

Hello everyone! Is it possible to directly measure the current running through a DC motor using the BTN9970LV shield? I tried finding the answer in the data sheet and user manual but I was unable to. Thanks for your responses!

This Q&A just discussed P/D Flash, AURIX™ MCU: Error Correction Code (ECC) support - KBA238244

My question: is there special ECC for  RAM and CAN relevant memory, e.g. Message RAM

Hi there,

Can you confirm whether the statement below is true?

"Where a watchdog timeout alarm (CPU or safety) is triggered the microcontroller will always reset"

I am learning about recovery timers and so far through my observation this appears to be true. I find the wording in the manual ambiguous however, where the word "ensure" is used in reference to this.

Thanks

请教大家一个问题

我现在做的boot程序在跳转app程序的时候，如果boot程序和app程序都没有使用中断的情况下可以正常跳转，但是boot程序或app程序有一方面使用中断的话就会进入到debug，boot程序或app程序单独运行时没有问题。下面按照串口中断举例。

调试状态下会卡在下图位置：

我想知道是哪个地方设置的不对或者少设置了什么地方。
