Hello,

I'm having issues migrating from an XTREME connectivity 1400 dev board to a custom PCB.

Having laid out and assembled a custom board, I'm not able to connect via SWD to start testing.

Toolchain is Rowley Crossworks. It's working fine with the XTREME board.

I have a few debuggers to choose from - Crossconnect with SWD adapter, the onboard debugger on the XTREME  board, and the debugger portion of an XMC1400 for Arduiono board. All work fine to debug the XTREME board, but when I try to connect to my own board, I get the following:

j-link Log
Executing get part name script
Loading target script file XMC1000_Target.js
Executing script GetPartName()
Identifying
ROM Table 0x20000fd8
Identifying

Cannot find debug component from ROM table

The CPU section of the board is as follows:

I get the same with any of the 4 possible positions for J68/69.

Looking at the schematics for the XTREME board, I can't see that I've missed anything. I don't have any connection for SWD reset, but it appears not to be required as it's not connected at all on the XMC1400 for Arduino debugger.

Oscillator doesn't appear to be running, but I think the processor should start from internal oscillator anyway.

Processors are from a lot of 50 purchased from Mouser, so should be good, markings XMC1404 200A R5G2124. I've tried several on different boards to no avail. 

I'm obviously missing something obvious, I'd love to know what!

Thanks

Hello all,

I have an issue trying to erase the Flash memory and specifically any sector above S8 of XMC4800. I am using the following function:

XMC_FLASH_EraseSector((uint32_t*)0x0C040000); 

and it completely freezes the microcontroller when running over this command. In the other hand the following

XMC_FLASH_EraseSector((uint32_t*)0x0C020000);

It succeeds. My firmware is running in S0-S4. The weird thing is that if I use the XMC4800_E196x2048 version it works but I my board has the XMC4800_F144x2048. Is anyone aware of any errata related?

Hi,

Are XMC4700 and XMC4800 binary compatible? That is a firmware written and compiled for XMC4700 could run on XMC4800, without recompile source code?

Thank you

Best Regards

Hi Guys,

Can you please confirm if we have to use the COL and CRS pins for Ethernet PHY with XMC4300?

In the reference design we see that the COL and CRS pins in XMC4300 are used for something else and the Pins on the PHY are kept empty.

Note: We will be using the Ethercat functionality.

Kindly suggest for design consideration.

Hello experts !!!

Here the program written for XMC1302 MCU want to debug it in the XMC1403MCU 

please help me to find the solution to start the execution  from application entry point from main function.

please find the document  below while debugging the XMC 1403 MCU it starts from Default Handler 

Regards 

Karthik.

Hi,
I want to run the SPI driver with DAVE4 Apps on my Relax-Kit. Therefore I have used the Infineon SPI example for DAVE4 to read and write data to the SPI-Flash.

As the example is written for a XMC4500-F144x1024 controller (144 pins), I have done the following steps to use the code on the relax-kit:
1. I have set up a new project for XMC4500-F100x1024 controller (100 pins).
2. After that I have added the same Apps as in the exsample to my project.
3. I have made all configurations according to the example and have assign the usic/0/channel/0 to the SPI_MASTER_App. 
4. I have copied the soure code to my project.
5. Make, running and debugging of the code works.

But even I have the signals on the SPI lines, there is on answer from the SPI-Slave device (SPI-Flash)!
With my DAVE3 project (and old SPI dirver) I can contact the same SPI-Slave device.
Also the signals look a little different to the DAVE3 signals, e.g. the position of the edges is different. All modifications to the configuration in DAVE4  App, I  could not solve the problem.

Is there a SPI driver or example with DAVE4 for the Relax-Kit?

Hi
We are using XMC4700 with LQFP-100 chip format. Our board had tree uarts where one them must use hw controlled flow control becuse paired unit has high priority interrupt that disturbs its UART RX interrupt. Our plan is to use the CTS signal to hold back the transmission of the XMC until the receiver is free to receive more data. Our XMC uses following pins this UART
RX  P5.1
TX  P5.0
CTS P5.7
RTS P5.2
My question is. Is it possible to use P5.7 as CTS because I can not find this pin defined inside the file xmc4_usic_map.h?
#if (UC_DEVICE == XMC4700) && (UC_PACKAGE == LQFP100)

Thanks in advance
