Hey swip sorry for the late reply, Are you still experiencing an issue when flashing your external board? You mentioned "getting error 33 when flash some basic code to the nRF52840 DK. I have notice that the green light is not perfectly solid. " Have you tried scoping VDD of the external board?

Hi,

Finally got what was going wrong :) Turns out it was due to the power supply with the USB without using a battery. There was a level drop each 400 ns approximately which was messing up with the SPI bus for the SD reader.

Thank you very much for your input and your help !

Now I use the circuit from this figure in the post to power the custom board and flash the code. Is it good to do it like this ?

I may have tried many things to solve my last problem and now I am getting error 33 when flash some basic code to the nRF52840 DK. I have notice that the green light is not perfectly solid. Do you think I may have fry my development kit ?

It looks like you are using S0S1 drive levels on SCK and MOSI pins, which are possibly insufficient; have a look at this post to see my suggestions on increasing the drive power; it helped another user.

The custom board is a two layers boards, nRF52840 is on layer one and molex on layer two. Do you think the vias between two layers can create a capacitor ?

Via are inductors, not capacitors. We still need a scope of the SPI bus.
I suggest that you desolder the molex SD card holder and solder the SD card to the molex footprint pad via wires. If this works then there's something wrong with the molex.

You should see 80 clocks with CS=high followed by a CMD0 command sequence with CS=LOW. The CMD0 sequence is 0x40, 4 times 0x00, and then 0x95 on MOSI.

Note that the SPI clock must not be faster than 400kHz, and there should be a pullup (internal or resistor) on MISO, as the sdcard will start up in open drain mode. Faster SPI clocks are only supported when the initialization sequence has finished.

no luck for the moment. What is your circuit ? Are you using your own custom board ?

Hi Swip - I am also having similar issues and wanted to see if you were able to resolve it

RE: unable to initialize to micro SD card using custom board

swip — Sun, 13 May 2018 11:06:01 GMT

Yes, it is where the problem is ie the app_sdc_init function. At the end of this function it will send 80 clocks without CS activated to switch into SPI mode

    // Send 80 clocks with CS inactive to switch into SPI mode.
    m_cb.cmd_buf[0] = 0xFF;
    err_code = nrf_drv_spi_transfer(&m_spi, m_cb.cmd_buf, 1,
                                            m_cb.rsp_buf, 10);
    APP_ERROR_CHECK(err_code);

There is no problem at this point in the code. Few lines of code after, it waits for the transfer to finish and throw an error that the last result is bad NRF_BLOCK_DEV_RESULT_IO_ERROR (1). But I can not see what happened during the 80 clocks.

I have tested the following things :

- with nordic DK I have welded a SD card adaptor directly on SPI bus. I have tested without sd card reader if it is working and the answer is yes ! This is exactly the same circuit than the custom board. No SD card reader.

- Using the custom board, I have downloaded a program that switch the pins (cs, clock, mosi, miso) to high and then enter an infinite loop which makes the debug led blinks. Using a voltmeter, I have checked that all pins deliver 3V when touching the pin on the sd card reader as shown

To sum things up :

The custom board is able to switch spi pins low to high (it is working). The code is working using the 'table' assembly (thank you Nordic). I don't have much ideas left to test.

The custom board is a two layers boards, nRF52840 is on layer one and molex on layer two. Do you think the vias between two layers can create a capacitor ?

You do not need to initialize the SPI. The app_sdc_init function in app_sdcard.c will do that for you. Can you capture the SPI bus from the point of first transfer?

Thank you haakonsh for your guidance. So from the first tests with debugger, the code goes with no surprise in the disk_initialize function in diskio_blkdev.c

Change happen between the two codes happen at the following lines

    ret_code_t err_code = nrf_blk_dev_init(m_drives[drv].config.p_block_device,
                                           block_dev_handler,
                                           (void *) (uint32_t) drv);
    if (err_code == NRF_SUCCESS)
    {
        while (m_drives[drv].busy)
        {
            m_drives[drv].config.wait_func();
        }

        if (m_drives[drv].last_result == NRF_BLOCK_DEV_RESULT_SUCCESS)
        {
            m_drives[drv].state &= ~STA_NOINIT;
        }
    }

    return m_drives[drv].state;

In both cases the err_code is NRF_SUCCESS. But when waiting in the wait_function() for the communication to happen, using the custom board the m_drives[drv].last_result switches from NRF_BLOCK_DEV_RESULT_SUCCESS to NRF_BLOCK_DEV_RESULT_IO_ERROR (1).

The nrf_blk_dev_init function seems to do the same things with the custom board or the nRF 52 DK.

If I understand correctly what does the initialise communication, it is only 80 times a sort of false communication to switch into spi mode with no CS pin activated. What ever the sdk_config file, the pins for mosi, miso and sckl are given in the main.c file, the spi mode is set to 0 and no pull up resistor is activated

from nrf_drv_spi_init function in nrf_drv_spi.c file

nrf_gpio_cfg(p_config->sck_pin,
                 NRF_GPIO_PIN_DIR_OUTPUT,
                 NRF_GPIO_PIN_INPUT_CONNECT,
                 NRF_GPIO_PIN_NOPULL,
                 NRF_GPIO_PIN_S0S1,
                 NRF_GPIO_PIN_NOSENSE);
    // - MOSI (optional) - output with initial value 0,
    if (p_config->mosi_pin != NRF_DRV_SPI_PIN_NOT_USED)
    {
        mosi_pin = p_config->mosi_pin;
        nrf_gpio_pin_clear(mosi_pin);
        nrf_gpio_cfg_output(mosi_pin);
    }
    else
    {
        mosi_pin = NRF_SPI_PIN_NOT_CONNECTED;
    }
    // - MISO (optional) - input,
    if (p_config->miso_pin != NRF_DRV_SPI_PIN_NOT_USED)
    {
        miso_pin = p_config->miso_pin;
        nrf_gpio_cfg_input(miso_pin, (nrf_gpio_pin_pull_t)NRF_SPI_DRV_MISO_PULLUP_CFG);
    }

I should add that I have tested 2 custom boards with 3 different micro SD cards without success for the moment.

Swip, I need you to debug disk_initialize() by single-stepping through the execution of its code. What you're looking for is the state and state changes that prevents the initialization of the disk buffer. Usually this is present in the parameters passed to the function, but it can also be a global state in the library.

The return value of disk_initialize(0) will tell you where in the function you returned from.

I did not see anything in the sdk_config, but it has 2k of lines so it's easy to miss an invalid setting. The debugging of disk_initialize() will tell us where to look next.

RE: unable to initialize to micro SD card using custom board

Check the SPI signals with a scope. We have no idea why this does not work either.

RE: unable to initialize to micro SD card using custom board

swip — Wed, 02 May 2018 15:09:35 GMT

Yes I did it. What I should look for in this function ?

I have checked the pins when initialising the SPI and it is alright. I thought that all useful things where declare in the code with the #define

#define SDC_SCK_PIN     42  ///< SDC serial clock (SCK) pin.
#define SDC_MOSI_PIN    36  ///< SDC serial data in (DI) pin.
#define SDC_MISO_PIN    45  ///< SDC serial data out (DO) pin.
#define SDC_CS_PIN      34  ///< SDC chip select (CS) pin. p1.02

/**
 * @brief  SDC block device definition
 * */
NRF_BLOCK_DEV_SDC_DEFINE(
        m_block_dev_sdc,
        NRF_BLOCK_DEV_SDC_CONFIG(
                SDC_SECTOR_SIZE,
                APP_SDCARD_CONFIG(SDC_MOSI_PIN, SDC_MISO_PIN, SDC_SCK_PIN, SDC_CS_PIN)
         ),
         NFR_BLOCK_DEV_INFO_CONFIG("PerfectStride", "SDC", "1.00")
);

What do I have to check in the sdk_config ? How can it work this one reader and not at all with another when using the same sdk_config ?

You need to step through disk_initialize() and see what's really going on.

I don't think this issue is related to SPI at all. My first guess is an invalid configuration of the fatfs or sd card libraries in sdk_config.

RE: unable to initialize to micro SD card using custom board

swip — Wed, 02 May 2018 13:46:59 GMT

Hi,

Right, the micro SD card comes from Kingston and it is a micro SD card HC with a speed class rating of 4. Here a link to the datasheet.

When using the custom board with the 104031-0811 reader from Molex the code return "Disk initialization failed." line 73 of the code pasted in the original message. Therefore, the error comes from the function disk_initialize(0) line 69.

If I try to sum things up :

I have two settings : one with the nRF52DK and this reader which works - and a second setting with a custom board and the Molex reader which does not. In both configuration I run the same code, with the same pins for the SPI bus.

I hope you have an idea to help me,

Thanks,

Loïc

[quote user=""]With my custom board the code can not do the initialization function[/quote]

What function returns what error?

We need a datasheet for your SD card.

RE: unable to initialize to micro SD card using custom board

swip — Sun, 29 Apr 2018 15:10:47 GMT

Hi,

Sorry for the misunderstanding.

On the custom board, the SD card reader is this one

And when testing with the nRF 52 DK I have used that one

With nRF52 DK is working but not the custom board. Same code, the only differences are : sd card reader and the CFLAG during compilation.

RE: unable to initialize to micro SD card using custom board

Turbo J — Sun, 29 Apr 2018 11:06:15 GMT

That SD card reader is supposed to work with 5V arduino, and may not supply the card enough voltage when run from 3.3V. It can also fry your NRF GPIOs when run from an actual 5V power source - these are not 5V- tolerant.
