  • Finally SD card issue is resolved.

    The issue was outdated schematic.

     

    For Rev-3 of this kit only

    They have added a transistor to switch on/off the SD card VDD. So all the fellow road testers kindly use the PORT_3 PIN_5 to turn on the VDD of SD_CARD and place the JP14 at 3V3 position for normal SD cards and Maxim Firmware examples will work without any additional modification.

  • That is really useful information, thank you. I'll run through it and have a go at modifying the PCB if I agree with your findings. It would be good to get the SDHC working.

  • There is a hardware issue thats why its not detecing SD card but after modifying sdk code you can also detect SD card presense but SDHC hardware module of mcu wont work with current pcb layout.

    Max32650 has port 0 pin 31 with SDHC card detection function but in current pcb layout it is connected with MAX32650 port 1 pin 17 which is also used for Max77650 SIMO buck boost Interrupt output.

    Infact, whenever we insert an SD card, we are shorting the MAX77650 nIRQ pin to ground.

    Another interesting finding is that SDK is configured correctly and using correct GPIO (0_31) for SD card detection. And the code is also detecting the presence of an SD card even when no SD card is inserted because port0 pin 31 is floating. Little hack to make sure it detect the presence of an SD card, you can manually connect the 0_31 to ground to tell the SDHC interface that SD card is inserted.

    Another pin to take care of is port 1 pin 2 because it is write protect detection pin for SDHC interface. This pin is also floating so it should also be connected to ground to avoid any undesired write protect enabling.

    For proper operation of normal SD card the JP14 should be at 3v3 position and SDHC bus voltage should be at least 3V0. (reference: https://www.sdcard.org/developers/overview/index.html)

     

    Unfortunately, even after configuring everything correctly the SD-card is not working.

  • Hi Mahmood,

     

    The SDHC-RAW program works from the MAX32650 board perspective....not sure what files are on my uSD card though.

    I then reformatted as FAT and added some files as a test.

     

    And then tried the SDHC-FAT program: I also get a null response, and again I think this is a card issue for me rather than the board not working.

    Both of these are via the Olimex ARM-USB-OCD-H unit. If you get anything useful back from Maxim can you please post it here as a good source of reference for the E14 community, thank you.

  • Yes, it will be helpful. Also can u simply run the sdhc example and confirm that it works.

  • I need to explain I'm a novice/beginner at this.

     

    Would it be helpful to you if I tried to re-flash my Olimex unit, and post screen shots of the process? What website have you tried to obtain the firmware from ?

  • Olimex debugger is stop working in the middle of firmware upload. I have shared the details and log file with Maxim and hopefully they will find a solution of this problem.

    So far I have tested everything except sdhc interface. I have tried everything so far but nothing is working for me. It will be a big help if you can provide any useful info in this regards.

  • Hi ,

     

    Is there anything else I can do to help you on this issue? or are you going to just write it up as is i.e. "the Olimex kit was broken and I used the Segger I had..."

  • I see.. yes, it does sound like a hardware issue if you've tried a few different machines.

  • Until today I have tested the debugger on three different window 10 x64 and one window 7 x64 and everywhere its giving same error when writing flash. Otherwise its detecting MCU type etc. I have tried almost every possible option so far and nothing worked for me.

    Yes I am working on the roadtest using segger debugger.

    Retail version of this doesn't contain this version of olimex debugger so its not a big issue.

    Earlier only time consuming problem was unavailability of up to date schematic of this kit and I have to verified and find some of the modified connections manually.
