Remora RT1052 DAPLink Programming

[@nix12m]

Hi Scott, thanks for all your work on this. I'm trying to get Remora on my EC300 controller and started to follow the instructions in your video. All went well until I looked for the Daplink firmware. The firmware I found is 164KB and my flash size is 128 KB. I see the file size in your video is 79KB. Now I find myself reading through all the posts on Linux Forum and trying to find the relevant file on GitHub. Is this video still relevant, or should I try a different approach? Please point me in the correct direction.

I feel you, I have a ec500 sitting here that's about to be thrown through a window. I've read about 100 pages of posts related to this. Googled everything I can think of, and am beyond frustrated right now with this. I pieced things together between this video and the thread over on the linuxcnc forum and I think I've got the st link flashed. But I can't get the python commands to work under either windows or Linux. There must be some magic that either Google or I don't know about.

The video is a a bit out dated now. The best way to flash is to use a Pico Probe with pyOCD. Works out of the box. python -m pip install -U pyocd pyocd flash . emora-rt1052.axf --target mimxrt1050_quadspi

But change the file name to be the latest version. I'm working on updating the documentation so people don't need to sift through the forum.

@@scott3d506 Thanks for the reply. I had a look at the Pico Probe... would prefer to stick to the STLinks. Is there anyway I can still do that?

[@nix12m]

@@brysonwitt4876 it is frustrating indeed. Thanks for sharing your experience. Sounds like you are a step or two ahead of me... I think my EC300 will become a side project now, need to get my CNC up and running again, so thinking of putting the old controller back in there. ugh

Hello there On my Digital Dream UC300 controller box the CONN light that indicates a connection with Mach3 is now always on. I have tried everything from uninstalling everything on my computer and reinstalling and setting all my configurations up in mach3 again. I think because the CONN light is stuck on that it is an issue with my controller. How can i reset my UC300 controller to factory settings ? Thanks

Hi Scott, I really appreciate all your great content! Can you please make a video on how to flash a EC500 with a RT 1052 with the ST-Link into a CMSIS-DAP probe. using pyocd? This would really help! Thanks

Hi Scott, is it possible to backup the original firmware before writing remora?

[@alessandromeyer4888]

Hey Scott, thanks for your great project and all the efforts that went into it. I have the NVEM v2 (actually says v5, anyway) could you tell me please where the programming headers are on these?

[@alessandromeyer4888]

Oh i realised you already have a video that contains that. Do you know whether the pins are the same on the non-STM32 boards?

[@alexparish937]

I would also appreciate some info on connecting to the NVEM board as I have a new and an older one. As a layman what are the differences I'm looking for. I cannot see any markings on the header. Is this the best place to be asking questions? Thanks

[@alessandromeyer4888]

@@alexparish937 I also asked on the linuxcnc forum and scott gave me an answer that wasnt fully able to grasp yet. 🙂

Hi Scott, I have a question for you, I get a No target connected on the STM32 ST-Link Utility when I plug in the St-Link V2. I havent used this utility before and am wondering if I'm missing something here. I've updated the firmware. Any help would be gratefully received. Kind regards, Rohan

[@scott3d506]

I can only think to check the wiring / connections.

Very cool !!

[@choco107]

Is this working with the EC500 aswell?

[@scott3d506]

EC500 is working with limited IO. I'm currently working through to have a specific firmware for the EC500 to have all IO available.

hi scott, do you have firmware files for nvum microprocessor stm32f207vct6, firmware for mvmpg console. I ask for help. thank you in advance.

[@scott3d506]

Just added it to the repo github.com/scottalford75/Remora-NVEM/blob/main/Firmware/fw_mach3_orig.hex

@@scott3d506 is it compatible with nvum? is this firmware compatible with win7?

[@scott3d506]

@@ЕгорШевелёв-ь3л Hi, the firmware is specific for the Ethernet version and for running LinuxCNC. For Windows you will want to stay with the original firmware.

[@dangervoid7435]

There is no bootloader file on your github nomore

[@scott3d506]

Yes, the DAPLink has not proven to be a reliable programming method and not recommended.
