Welcome to the Infineon Developer Community

Hi all,

I had a question while studying the UART function of MTB.

I understand that the UART API is divided into two categories: High-level and Low-level.

In MTB, I could choose which API to use.

However, even if I chose the High-level API mode and only use the Low-level API to write firmware, UART works normally.

Similarly, although I chose Low-level API mode and only use the High-level API to write firmware, it still works.

So, what is the meaning of choosing the MTB API mode as High-level or Low-level?

Thank you for your support,

Regards,

Dear fx3 experts! I encountered a problem during development.

I used the 3014 chip, and the data stream was transmitted from FPGA to 3014 and then output through UVC.

When I use the Windows system, the video stream appears to be normal. But when I use the Mac system, the video stream will experience jitter. The video stream is good and bad at times, and this time is random.
I use manual DMA and print the values of prodCount and consCount in UVCAppServiceThread_Entry function. I found that when the video stream shakes, it does not enter the CyFxUVCDmaMultiCallback function, and the values of prodCount and consCount also increases(about 60).
The jitter phenomenon looks like that: the image in the upper part of the video stream has been updated, but the image in the lower part has not been updated, resulting in misalignment.
It looks like packet loss and something else, I don't really understand how to solve it.
Could someone give me some advice? Thanks.

报错使用的工程是基于ASCLIN_UART_1_KIT_TC397_TF这个demo，添加了一些autosar工程和生成代码。

使用的ADS版本是1.5.2，编译完成后没有报错，随后进入到Debug时，弹出以下提示：

 随后我又下载了demo进行实验，发现demo能够正常进行调试：

这个debug问题该如何解决呢？

你好 我做了5块板子 用的3014 ，第一次上电 只有一块板子 可以正常启动，正常烧写ram 和 flash  ;  2块板子 PC上完全识别不了 ；  2块板子 ，PC能识别到 ，烧写ram是可以的 ，但是烧写Flash 失败  ；用 USBBulkSourceSink.img 这个固件烧写ram ， C++ Stream 软件里面也不能识别Endpoint   ； 

请问有可能是哪些原因造成的 硬件上该怎么排查 

Using AURIX TC377TX, Bootloader and APP are stored in 1M space from 0x80000000 to 0x800FFFFF of PF0. When APP erasing 128 Logical Sector starting from 0x80100000 of PF0, Program Fetch Fetch Fetching Error (PSE) Trap is causing and Fetch Bus Error (FBE) is raised in CPU- >CPU0- > PMI- > PSTR (Program Trap Register)

But erasing the 128 logical starting at PF1 0x80300000 is fine.

Check the 2MPFLASH SPACE STARTING at 0x80100000 and there is no code.

Can you tell us why the Fetch Bus Error is dangerous? How do I find out what does it mean?

买到一批IGBT模块FF450R12ME4 有很多瑕疵。背板有很多大面积黑点，划痕，螺帽口粗糙，请问是否属于正常状态。 有没有类似的文件说明。

I am trying to use the DAVE IDE to flash an updated firmware configuration to the XMC4700 on the Distance2GoL demo kit. When I press "debug" (which seems to be the button to press to flash) I keep getting a J-Link driver error even though the Distance2GoL documentation suggests that no J-Link debugger is necessary to flash. Can you help me resolve this? My overall goal is to configure one of the I2C lines on the Distance2GoL with an address, so that I can write to it from an Arduino and eventually receive data from it.
