16:22 <lehel> hello group, can i get help here ??

16:24 <jybz> lehel: it depends.

16:25 <lehel> i think i bricked an nrf53840 dongle, was trying to change the bootloader to adafruit

16:26 <lehel> i made a text file with the steps i tried, can i paste here ?

16:27 <jybz> lehel: Don't paste there, paste it online and give a link

16:27 <jybz> (like : cat ./yourfile | nc termbin.com 9999 )

16:28 <lehel> https://pastebin.com/160QPY2B

16:30 <jybz> Should not be bricked. I hope someone can help you there.

16:35 <lehel> i hope so, the red led is not flashing anymore, can i post my problem on github too ?

16:41 <PaulFertser> lehel: what tools do you have?

16:41 <PaulFertser> What github project do you mean?

16:42 <PaulFertser> lehel: it's good you keep the log of your steps

16:42 <lehel> https://github.com/openocd-org/openocd/

16:43 <PaulFertser> lehel: no, issues are not reported there. And I think yours is not an issue. What bootloader are you writing and how you plan to interact with it?

16:44 <lehel> i am trying the pca10059_bootloader-0.6.2.zip from https://github.com/adafruit/Adafruit_nRF52_Bootloader/releases

16:44 <lehel> i would like to try circuitpython

16:45 <lehel> about the tools, i have a raspberry 4 :)

16:46 <PaulFertser> lehel: ok, judging by your log you're all set and good to go. How do you plan to talk to the bootloader if you manage to flash it successfully?

16:49 <PaulFertser> lehel: try to run the "reset halt; flash write_image erase /path/to/file" command again.

16:49 <PaulFertser> And show the output

16:50 <lehel> if i flash the bootloader after the reset, there should be a drive visible where i can copy the uf2 file from https://circuitpython.org/board/pca10059/

16:50 <lehel> one moment

16:54 <lehel> for the reset part i got: target halted due to debug-request, current mode: Thread; xPSR: 0x01000000 pc: 0x00000a80 msp: 0x20000400

16:54 <lehel> the result of the flash write_image is the same

16:54 <lehel> Flash write discontinued at 0x00025de8, next section at 0x000f4000; Failed to write memory at 0x4001e504

16:58 <jybz> 0x4001e504 isn't it a big number ?

17:01 <lehel> if i run the flash write_image i get Failed to write memory at 0x200006c8

17:01 <PaulFertser> jybz: probably flash is mapped there

17:01 <PaulFertser> lehel: but it's not the same, in your paste flashing failed at address 0

17:02 <lehel> the Failed to write memory at 0x200006c8 is changing

17:03 <lehel>  0x20001b08, 0x200006c8, 0x4001e504, 0x20001e70

17:04 <lehel> and the Padding image section changing too with every try

17:05 <PaulFertser> lehel: probably just try lower adapter speed?

17:05 <PaulFertser> Padding image section shouldn't be changing though.

17:06 <PaulFertser> lehel: please use some pastebin to show full logs

17:09 <lehel> https://pastebin.com/L5gLTUuj

17:09 <lehel> lowered the adapter speed to 500

17:16 <lehel> i think its worked

17:16 <lehel> lowered to 100 and the verify was successful

17:16 <jybz> \o/

17:19 <lehel> its blinking:)  thank you very much for your time

17:20 <PaulFertser> I wonder why so low speed was needed.

17:21 <lehel> maybe the connection, wires

17:27 <lehel> thank you again, have a nice evening
