Does the FCF block have to be skipped somehow? Info : starting gdb server for kx. Any help would be much appreciated. Tickets: My problem is due to programming all of the flash at once using the following. A different algorithm is needed for the FCF block at 0x - 0x40f. Could somebody tell me where the tcl proc "program" code is located so that I can write a similar proc myself to program the different sections.

I am confident that I then should be able to solve my problem. Let's hope it's not the case. I tested programming with our fresh git master code in almost identical setup: FTDI based SWD resistor hack and MK22FX, just the blink test is not arduino based - and gues what - programming works:.

Looking at your objectdump it is most likely the linker script holds the secret. I would now like to delve into this some more as it is a great learning experience. I inherited this project. It is using Arduino and running a hack of the Teensy3 core, which is where the linker script is coming from. The version of Arduino is 1. What build system did you use? I would like to duplicate what you have done and then I think we are almost there.

I will post my progress as I go. My code uses Kinetis SDK. So far I have not bricked any chips yet so luck has been on my side. Are the tomvdb of EduBot fame.

Or force it via parameters. Info : at91samd21e After that bootloading was successful and i can now program the board with usb.

I can't for the life of me seem to figure out how to write a program to a Same54 same device class as samd51 using openocd. I have an elf, bin, hex file generated by Atmel studio but I don't know which section of memory to write to. I had assumed that writing to the first memory bank would be fine but this does not appear to be the case.

Have you successfully put code on the Samd51 and not just a bootloader made by someone else? But the code does not run after after flashing like it does from the Atmel Studio programming window.

I am able to program. I tried Michael Dietz's solution without success.

Removing flash protection from the nRF52 using JLink + OpenOCD

The dap process should work, but I can't get it to. I must be missing something obvious, and any help would be appreciated. If so could you please let me know how? Edit: I'm taking another look at the product specificationSection 16 page 70Debug and Trace. See the Arm Debug Interface section 2.

So now I need to figure out: 1. I'm going around in circles. Edit 4: The patch that I applied to openocd was incomplete. I will post an answer once I am able to fully replicate what was done to get it working. The answer is to modify the openocd source to add nrf52 support.

Basically add definitions and functions for the NRF52 to the nrf51 driver file. Then, use the nrf51 commands to write dap apreg 1 0x04 ….

It certainly agrees with the 2 I posted, and the product specification, but doesn't get me closer to my goal :. The goal is to recover? Looks like OpenOCD don't have a command similar to recover with nrfjprog. Then, use the nrf51 commands to write dap apreg 1 0x04 0x Turning up debug output on openocd also helps.

So this worked very nicely. Not sure why atsame5x. Probably atsamv. I can test E5X support if it lands somewhere. Can you please add a comment to Gerrit and possibly test this patch with other related devices if you have any?

What do you mean by it wasn't removed from anywhere - I couldn't find it from latest version. It wasn't removed from the sources as it wasn't ever merged in the first place.

It's a pending change and it needed some review and testing. If you add your feedback to the Gerrit change it would be nice. Oh no! Some styles failed to load. Help Create Join Login. Operations Management.

Why this is not a duplicate Some people seem to think this question is a duplicate, but there is an important difference:.

In the end we got a solution. The purpose of that question is therefore fulfilled. I've edited the conclusion-section of that question to clarify this.

The question on this page is all about what firmware is being put on the probe - and more in particular - what is wrong with that firmware such that it malfunctions with OpenOCD.

Please take your time to read both questions completely not just the titles if you think this question is a duplicate. At first I had some trouble updating the probe's firmware, but that has been solved in my previous question see How to update the SWDAP firmware? The probe arrived to me with some firmware on it. I've plugged the probe into my computer while holding down the reset button. This way, I could access firmware. On the original firmware, the probe works perfectly with OpenOCD.

This is my OpenOCD startup command:. Note 1: I've splitted the command over two lines for readability. This works perfectly. All is well. I'll first say a word about the firmware name convention. The names have a specific meaning:. The Probe Chip must match the chip on the probe itself. For me, that's the LPC11U The Target Chip must only match the target chip if you're planning to use the drag-and-drop flashing feature.

As I'm not using the drag-and-drop flashing, this choice makes most sense to me. I've used exactly the same OpenOCD startup command as before, with exactly the same config files.It can be used with Photon, P1 and Electron devices and this document will describe using it for tasks like programming flash and saving configurations. This is helpful because it only requires two pins D6 and D7. It connects easily with the included ribbon cable. Finally, there's the Particle Programmer Shieldprimarily designed for the Photon but can be used with the Electron.

It can only be used with 1st and 2nd generation devices Photon, Electron, and Corenot with mesh devices. The easiest way is to enable DFU mode blinking yellow.

This works even if you have a P1 without a USB port. Even if you don't use the pins, you will likely have problems using SWD in normal operating mode breathing cyan. With the Particle Debugger positioned like this, USB connector toward you and the headers facing up:. The pins on the connector are numbered this way when you have the programmer positioned so the logo is upright and the notch is on the bottom of the pin connector.

It's used to detect the device voltage, and if you don't connect it, it does not work reliably. One of the common uses for a programmer is fixing the situation where the boot loader gets corrupted. And the main LED does not light. Select Connect from the Target menu or use the toolbar icon.

It should look something like this:. The bootloader is different for each type of device and changes infrequently. Download the appropriate one for your device:. Use the Program and Verify menu item from the Target menu. The dialog looks like this:. Make sure the start address is 0xselect the bootloader binary, and select Start.

That's it. If your flash is very corrupted, you may also need to flash system and user firmware as well, as described below. For the Electron running 0.
