Now the code in the application part has added the buttonless_dfu function, which has also been successfully implemented. But I ’m not familiar with serial_dfu, I don’t know how to continue to add serial_dfu function. And how to achieve coexistence of ble_dfu and serial_dfu in bootload code？
Hi June,
You can have a look at this case: https://devzone.nordicsemi.com/f/nordic-q-a/35431/dfu-over-ble-and-usb
I have an example for SDK v15.2 there. To find how to enter DFU bootloader mode from application, please study the ble_app_buttonless_dfu example. Check function enter_bootloader() and then ble_dfu_buttonless_bootloader_start_prepare(). The GPREGRET register is written before the application reset and enter bootloader.
Hi Hung Bui，
I have added the serial_dfu code with reference to this routine, and now I have a few questions:
1、Does uart need flow control during serial dfu? I am currently turning off serial port flow control because my hardware does not have two pins for flow control
2、In normal application operation, in addition to the buttonless method, I can also enter the upgrade mode by pressing the button. After pressing the button, I performed the following operations:
err_code = sd_power_gpregret_clr(0, 0xffffffff); VERIFY_SUCCESS(err_code); err_code = sd_power_gpregret_set(0, BOOTLOADER_DFU_START); VERIFY_SUCCESS(err_code); // Signal that DFU mode is to be enter to the power management module nrf_pwr_mgmt_shutdown(NRF_PWR_MGMT_SHUTDOWN_GOTO_DFU);
Is this correct?
3、After entering the upgrade mode, what nrfutil command is used to upgrade the zip package into the chip?
By the way, I need the code to run properly at 52840dk !!!
Hi June,
I found that it was because of this definition NRF_DFU_PROTOCOL_REDUCED 1 in sdk_config.h in SDK v15.3 causing the issue.
Please set it to 0 if it's 1 in your sdk_config.h , after that it should work.
I attached here the hex file for bootloader and the Keil project in SDK v15.3 that I used.
It's the same private key as I sent earlier. pca10056_ble_uart_debug.zip
Hi Hung,
Unfortunately, the problem still exists.
Although I have executed MSDDisable, DFU still fails. The following is the error message, same as before:

But at the same time SDK15.2 is normal (SDK 15.2 and SDK 15.3 are configured with 115200 baud rate and HWFC is turned on). By the way, I used your 15.3 code project to compile without any changes (just replaced the key.c that matches my environment), the problem is still not solved.
Please capture the RTT log as well.
Which baudrate did you test ? Have you tested with or without HWFC ? Could you test with very small image ?
Also please try testing with my bootloader.hex file inside the .zip.
When you test SDK v15.3 with the stock bootloader (not the combination) do you see the same issue with "Did not receive checksum response" ?
Also please try testing with my bootloader.hex file inside the .zip.
When you test SDK v15.3 with the stock bootloader (not the combination) do you see the same issue with "Did not receive checksum response" ?
When you test SDK v15.3 with the stock bootloader (not the combination), everything is normal.
In addition, I cannot use bootload.hex to test directly, because the key in the project is different from the key in my environment.
So I replaced the key in the project with a key that matches my environment and generated hex, and tested it with this hex.
Hi, Hung
Now, when the HWFC is turned on, the DFU can be normal, but once the HWFC is turned off, the DFU will fail.

Now I can be sure that this must not be a hardware problem, nor a problem with the nrfutil tool. I also made sure that I implemented MSDDisable. And when the HWFC is closed, the baud rate is reduced to 9600, and the DFU will fail. Then turn on HWFC, DFU can succeed again.
Do you have a solution to this problem? I've been knocked out by this problem...
Hi June,
I'm not sure what could be wrong here as the test here worked fine.
I have modified the nrf_dfu_serial_uart.c a little bit but I don't think it would help much. Please try using the file I provided here.
I can see in the log there is a printing of a long "ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ" could you check why ? Did you modify anything creating that ?
THere is an error "0x00001" that we need to investigate.
Please add DEBUG into the preprocessor definition in the project setting so that we can have more logging information. If there is a complain about app_error_save_and_stop() you can just change it to "while(1);"
