Hi,

Please make a new question.

Hi, I also encountered this problem, I expanded "NRF_DFU_SERIAL_UART_RX_BUFFERS", the problem still exists, I use "UartSecureDFU.exe COM8 dfufile.zip -v -v -v -v" and "nrftuil" to upgrade my debugging upgrade package, through the UartSecureDFU.exe "log, the same as my serial port. May I ask how to solve this, I use 52833 17.0.2 sdk

Hello, may I ask how you finally solved this problem? I am debugging 52833 now, and after trying, I also reported the same error type as yours.Below is my error log

Hope it can help

Hi,

The next thing to look at then is this:

<error> app: Received a fault! id: 0x00004002, pc: 0x00000000, info: 0x2000FF40

Which is printed by the fault handler, and that is called for NRF_FAULT_ID_SDK_ASSERT (0x00004002). What does the info struct (at 0x2000FF40) contain? And what does the call stack look like if you set a breakpoint in the app_error_fault_handler()?

Hi,

Thank you for your help, I can solve the Serial error. But my Serial DFU application still has not worked

Could you share some information about your DFU sequence? What am I missing on it?

Hi,

After disabling Hardware Flow Control, the Serial error is solved.

But my application is still stopping at:

I'm Also get that Error, when trying to update nRF52832 by UART. Do you solve it?
with Error, Fail to send data over serial interface, try to turn of Hardware Flow Control, it solve in my case

Hi,

That is one less error, at least. The first error is "Failed to send data over serial interface!", right? This comes from line 141 in components/libraries/bootloader/serial_dfu/nrf_dfu_serial.c (nRF5 SDK 17.1.0). I suggest focusing on that first. Can you modify line 141 to also print the error code? Perhaps that will give some indication on what the problem is.

Hi,

I increased NRF_DFU_SERIAL_UART_RX_BUFFERS, it can pass the Failed to allocate buffer error.

However, nothing further took place.

Hi,

This error comes from the call to nrf_balloc_alloc() on line 127 in components/libraries/bootloader/serial_dfu/nrf_dfu_serial_uart.c. I am a bit suprised that you get it if you are using an unmodified bootloader, but you can try to increase NRF_DFU_SERIAL_UART_RX_BUFFERS in the bootloader's sdk_config.h to a higher value and see if that helps?
