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

您好，

请问如何才能用miniWiggler 下载调试的JTAG连接方式进行下载呢？

Hello 

Can we allocate 2 nodes on MULTICAN_CONFIG_0, and operate all message objects of both the nodes using only one CAN_Rx and CAN_Tx through transceiver??

The current TC397_TFT v1.0 development board uses the TC397 A step of the chip, but I see ADS are TC397 B step routines, I will ADS in a few examples compiled and burned to the development version, can not run normally, respectively, through the TASKING and winIDE DEBUG found that the chip startup process will enter the Context Maneger Error Trap, the following figure belongs to, please ask! Please ask:

1. For Context Maneger Error Trap should be solved in what way?

1. Current ADS 1.9.20 supports TC397 A step chip, if not support and TC397A step corresponding to the example tutorial?

2. What is the difference between TC397 A step and TC397 B step?

Hello, everybody:

I encountered the following problem, read the value in the register, check the register is "0x80000e23", but after reading, the first bit is not read, only read "0xe23", the type of the variable used to receive the value of the register is ( volatile uint32 )

Dear All，

               I use the DAVE ide v4  with the nano library， calling the SPI-MASTER-EnableSlaveSelectSignal() and SPI-MASTER-DisableSlaveSelectSignal() functions cannot raise or lower the CS pin of SPI. However, when sending data through SPI, when using an oscilloscope to check the status of SCL and MOSI pins, they generate waveforms that are normal, but the CS pin remains in a high level state. 

              Configure this CS pin as an IO port, manually pull up or down the CS pin, but use the BUSY flag in the TBUF register as the completion of sending. When pulling up the CS pin, there will be a situation where there is still one byte that has not been sent, but the CS pin has been pulled up.

             What may be the reason why the two API functions generated by calling cannot control the CS pin state; How can I avoid manually raising or lowering the CS pin when there is still one byte of data not sent?

Thanks.

大家好！

官方程序里的延时函数Delay_us(uint32 delay_time_us)，在实际测试时，有个奇怪的现象。

测试程序看门狗设置1008ms，测试程序延时方式如下：

1. Delay_us(500000); (void)WDT1_Service();     //延时500ms，喂狗
2. Delay_us(600000); (void)WDT1_Service();     //延时600ms，喂狗
3. Delay_us(1000000); (void)WDT1_Service(); //延时1000ms，喂狗

其中，1，3能正常工作，第2项延时600ms喂狗，程序没有喂狗成功，程序不工作。

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

Hello,

I am trying to flash littlefs filesystem on thze qspi external serial flash memory in XMC7100 V1.1.

As I see library mtb-littlefs is not included in the XMC7100 kit.

• If I download any one of the PSoC6 kit and add the mtb-littlefs lirary to my project for XMC7100 v1.1 board build and run, Will it work?

1. How do I mount the Littlefs to the external serial nor flash attached through qspi to the board ?
2. I have limitation in using shread git repo therefore I have a local content storage added.

These are the errors when I try to add the PSoC6 library throught BSP Assistant:

Could someone help me with another littlefs wrapper for the littlefs filesystem for XMC7100 kit?
