USB Dfu cause hash not match issue.

[weizhen]

hi,

I am working on nrf52833 dfu. right now I received an error 

raise NordicSemiException('Extended Error 0x{:02X}: {}'.format(resp[3], data))
pc_ble_driver_py.exceptions.NordicSemiException: Extended Error 0x0C: The hash of the received firmware image does not match the hash in the init packet.

it happened when 96% finished.

my dfu memory settings is :

FLASH (rx) : ORIGIN = 0x74000, LENGTH = 0xA000
RAM (rwx) : ORIGIN = 0x20002ae8, LENGTH = 0x1d518
uicr_bootloader_start_address (r) : ORIGIN = 0x10001014, LENGTH = 0x4
bootloader_settings_page (r) : ORIGIN = 0x0007F000, LENGTH = 0x1000
uicr_mbr_params_page (r) : ORIGIN = 0x10001018, LENGTH = 0x4
mbr_params_page (r) : ORIGIN = 0x0007E000, LENGTH = 0x1000

and my application is :

FLASH (rx) : ORIGIN = 0x27000, LENGTH = 0x4D000
RAM (rwx) : ORIGIN = 0x20000000, LENGTH = 0x20000

I also post my info here. https://devzone.nordicsemi.com/f/nordic-q-a/64101/nrf52833-usb-dfu-bootloader-does-not-go-to-the-application 

the pca10100_usb_debug is the one I start from pca10100e_usb_debug, this one, I can flash, and the application and bootloader can be writed into memory, but the application is not run. then the pca10100_s140_ble_debug_usb is the one I start from pca10100_s140_ble_debug, this one the nrfutil do not give any problems, but after flash, the application is not on memory.

Hi Weizhen, 
I have made an example for USB DFU on nRF52833. I attached the project (pca10100_usb_debug_833.zip) here. 
It's made on SES and was modified from pca10100e_usb_debug. But should be straight forward to port to gcc. I would suggest to compare the .emProject file and the flash_placement.xml file to see my modification and apply the same to your gcc Makefile. Main changes were flash size and address, ram address and size, hard floating point. 

I also attached the .hex file I used (mbr, bootloader and the dfu .zip file) so you can test on your side. 

Before you test, please make sure to do a chip erase.

hi Hung Bui,

I tested with the bootloader file you give me, it can flash the blink flash, and it can runned. but for usb debug package, it cannot flash, and return an error message.

also with serial window open, I have not see any debug message print out, are you using uart debug or rtt debug?

Hi Weizhen, 
Could you explain what you meant by "but for usb debug package, it cannot flash, and return an error message" ? 

You supposed to unzip pca10100_usb_debug_833.zip put that into the bootloader example in SDK and then compile the bootloader using Segger Embedded Studio . Do that you will get the bootloader .hex file. 

If you want to compile using gcc you would need to modify your make file according to what I did in the .emProject  file and flash_placement.xml file.

hi Hung Bui,

after check the pca10100_usb_debug_833.zip you send to me. I switch the log mode I used from uart to rtt, and it works. then I do more test and found maybe there is some issues with uart log. based on my result, turn off the log or using rtt log both works, but using uart log causes the issue.
