Hello All,
I am using XMC4700 Infineon for my Application development need to store some data to SD card, I want to use it with SPI, and without any interrupts. So could some one please provide the sample app for it. where the communication could happen over SPI and without any interrupts been used ?
Thanks ,

Show LessI am having a compile issue with my DAVE project. I simplified my code so it is easy to see the problem.
The attached project gives the error during build. Nothing shows up as a mistake in the individual files. If the "functions" file is removed from the project then it builds fine.
Any help to identify the issue would be very much appreciated.
Implementation of XMC4400 in our Air Conditioner circuit.
https://www.infineon.com/cms/en/product/evaluation-boards/kit_xmc_plt2go_xmc4400/
Currently my requirements are as follows
Operating voltage 5v dc, Analog inputs: 2, Digital inputs : 9, Digital Outputs: 4.
Digital inputs include push buttons, status monitoring of devices connected. Digital Outputs include relay energization, lamp control and NO/NC contact.
Referring page no 12, Currently GPIO pins available are 4 so please advice the way forward either to use any auxiliary board to fulfill the application or existing pins can be utilized.
I am trying to use the DAC of the XMC4200 together with the DMA, but the data is not being transferred by the DMA controller.
The DAC channel 0 is configured in Data Mode with internal trigger and a frequency of 24kHz. The Service Request, Run and Analog Enable bits are set.
The DMA Line Router (DLR) is configured with line 1 with RS1 = 5, which is DAC.SR0. Line 1 is enabled with LN1 set.
The DMA channel 1 is configured with the Destination Address Register set to 0x48018014, which is the DAC input register. The CFGH.DEST_PER is set to 1 to use DLR line 1 and CFGL.HS_SEL_DST is set to 0 to select Hardware handshaking.
The DMA is enabled with DMACFGREG.DMA_EN set.
As far as I know everthing is configured correctly, but it does not work!
The application is a modified version that used the DMA to send the data to a USIC and that works correctly.
Does anyone have any ideas where the problem could be?
Show LessHi,
What is the ramp-up time/slew rate for XMC4800 on VDDP power-up?
The XMC1400 datasheet had this information, but not the XMC4800.
If this parameter is not specified, what happens if VDDP and VDDC are above the reset threshold voltage (VPOR/VPV) but not above the operating voltage (3.13V)?

Hi Infineon.
Are there any Infineon non-automotive MCUs that have built-in SRAM with ECC?
My understanding is that only XMC7000 series(XMC7100/7200) has built-in SRAM with ECC at this time.
Is my understanding correct?
Best Regards.

Show LessHello,
Currently, I am working on XMC 4400 Platform2Go kit and in future I will work on XMC4400-F64K256 MCU.
I want to understand the major limitations of XMC 4400 MCU CAN message Tx/Rx IDs:
As refer to DAVE IDE Apps:
1. Using CAN Node App, we can create total 32 message object, Correct?
2. Using MultiCAN App, we can create total 64 message object, Correct?
As referring to reference manual,
3. It is mentioned that XMC4400 supports 64 message object and 0x7ff message IDs (i.e. 2047). Then, what is correlation between message object and message ID?
4. Do we have limitation to 64 tx & rx message objects only? i.e. we will able to transfer or receive 64-bit 64 messages only where message IDs can be anything between 0x0 to x7ff (i.e. 0 to 2047)-> I need confirmation over here, please rectify my understanding if I am wrong.
||==>>Yes, It may be true that we practically don't need 64-bit data to be transfer over CAN (in special cases may be need)- But let consider I need 64-bit 100 messages I want to transfer or receive in that case how I can Tx/Rx with 64 message objects.
Please, provide your suggestions.
Thanks & Regards,

I found one answer regarding implementing a bootloader over ethernet that didn't actually answer the question.
Can an XMC device have the flash programmed over an ethernet interface?
My application is an embedded device mounted in an industrial enclosure that is difficult to access without bringing down the customer production line due to lockout/tagout requirements. The embedded device is networked to a host PC with 100Mb Ethernet as the only means of communication. I'm looking to update an older design that doesn't currently have any means of updating the FW without physical access to the PCB and want to build in a remote update capability.
