@Grandgogo: What do you mean ? Do you mean if you generate the hex file from keil it worked fine ? I'm a little bit confused on what works and what doesn't

@Hung was able work with different sample .hex files generated from keil(pca10040, with soft device 132 ),

@GrandGoGo: Could you send me the hex file so I can test here ? Would the nRFGo Studio works with any file (for example the example hex file in the SDK mentioned in the question ? ) It's a little bit strange because under the hood, nRFGo Studio use nrfutil to do DFU.

@Hung

Could you let me know which hardware board you are testing with ? PCA10040

Do you see LED 3 turned on when the bootloader start ? LED 3 on in bootloader mode

You can try to read out the flash and send me the hex so I can test here ? how i can send the complete flash data

**When i am using zip file provided in SDK getting below error **

I guess a UART port sniffer may help.

I tried using nrfutil in a Windows machine and it worked. This means there is probably an issue with the serial port configuration in Linux, but I couldn't solve it yet.

Even i am facing the similar issue on windows as crespum,

@Crespum: I just tested by following the same steps on a Windows machine and DFU process was fine. My nrfutil on Windows was v0.3 but I don't think there is much change in v0.5.

You may need to sniff what happens on the UART lines or debug the bootloader to see where it stuck. Could you check if LED 3 is ON ? To enable debugging with bootloader you can have a look at question F here.

I've tried the UART example and it works on both directions (RX/TX). I've also tried to program the SD before the bootloader without any luck.

I'm also sure the bootloader is starting because I successfully tried to switch the default LED. Nevertheless it hangs at some point because the LED never turns off as it should after the update.

@Crespum:

Have you test and make sure UART worked normally ? There is an UART example in this folder: \examples\peripheral\uart

Could you try to program the softdevice before programming the bootloader ? Have you made sure the bootloader started properly ? You can check by printing out something from the bootloader on UART.
