ST25PC-NFC software is not detecting the ST25DVKC-DISCO board

[srikarthik0601]

To perform the demos, the ST25 Android app is asking me to upgrade the firmware by PC and telling it can't be done by the Android Application, but when I open the ST25PC-NFC software, it doesn't detect the reader and hence can't upgrade the firmware. I have connected using both STLink USB(MicroUSB) and MCU USB(MiniUSB) but both of them don't work. Is there any other way to upgrade the firmware using STM32CubeProgrammer as I am able to connect using the STLink USB, and I also have the binary file for upgrade?

Hi,

the ST25DV64KC-DISCO features the ST25DV64KC dynamic NFC/RFID tag thus the ST25DV64KC-DISCO is not an NFC reader board and cannot be used as a reader board by the ST25PC-NFC software.

The ST25DV64KC-DISCO FW can be upgraded by drag and drop programming (a USB mass storage should be present on your PC once the STLink is connected) or by using the STM32CubeProgrammer.

See also User Manual UM2949 for information related to the Firmware Upgrade demo through FTM. To use this demo with the ST25PC-NFC, a reader board needs to be connected to the PC.

But in the UM2949 document, the board was getting recognised by the ST25PC-NFC software right?

I haven't done firmware upgrade using STM32CubeProgrammer before and I don't want to mess it up. So the start address should be 0x08000000 this or something else? and also should I do a full chip erase or only selected sectors? If selected sectors, please also let me know which sectors.

Thanks!!

When I try to update using the ST25 NFC app as given in the UM2949 manual, this is the response I get as shown in the picture and even though I tried with the embedded firmware in the application, all I get is no response received. Please let me know if there is any solution for this, I can't use any FTM demos.

Hi,

as explained in the UM2949, a reader such as the CR95HF is used with the ST25PC-NFC to communicate with the ST25DVKC-DISCO board. See for example:

Hi,

you just need to download from st.com the firmware package indicated in the popup window: i.e 

and then upgrade the ST25DV64KC-DISCO FW (a USB mass storage should be present on your PC once the STLink is connected: just upgrade by drag and drop programming. If using STM32CubeProgrammer, just use the default parameters).

I have dropped the firmware upgrade file in the board, now it just went blank and doesn't reset as well. I have tried with STM32Cubeprogrammer as well and has the same output. What should I do next?

Hi,

can you take a picture of your board and sent it to us? what is the identifier written on top right corner of the mother board (MBxxxx-x)?

Hi, nevermind this I fixed it, the problem was I uploaded the firmware upgrade demo file instead of the general ST25DV demo file, when I uploaded the general file, it started working. Thanks for helping me out. I need another help, how do I upload pics on the board without the reader board?
