No Flashing Blue Led on Mks Gen L Board

MKS GEN 50 upshot uplading firmware

Hello everyone! I would actually appreciate your help!

I am not developer, I just follow guides and try to make the best of it.

I bought an MKS GEN L v1.0 board in club to replace the one-time motherboard of my Ender iii 3d-printer. It was supposed to have a bootloader, so the job seemed easy. However, when I tried to upload Marlin on it, I got the following message:

avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_getsync(): timeout communicating with developer

All parameters are right: board (Arduino Mega), processor (ATMegaA 2560), COM port (COM5, programmer (AVRIS mkll) etc.

I then tried a dissimilar pc. Same thing happened.

So i found a method where I would upload a new bootloader, using an Arduino Uno and the Nick Gammon's Atmega_Board_Programmer. That went well, and the new bootloader seemed to load correctly on the MKS. The I continued the usb cable to the MKS and retried to upload Marlin. Aforementioned bulletin: avrdude: stk500v2_ReceiveMessage(): timeout. When ArduinoIDE finishes compiling and tries to upload, a blue led light on the board turns on, and later on each timeout, it turns off…..

I am at loss.. I am starting to believe that at that place is something wrong with the usb port of the board. Is there any way that I effort to upload the firmware via the Arduino?

Thank y'all all….

I'm getting this fault when trying to build past pio.
when trying to build 'manually' i'm seeing an LPC1768 Environment fault – I need some assist to get around this plz.

any assistance will be greatly appreciated

I can't get around it and i'one thousand not sure whats causing it, I ready the env to a LPC1768 and board to GEN_L,
why am i however getting this error?

Right, first obstacle been passed – had to add together to Marlin-bugfix-2.0.x/.pioenvs/LPC1768 new file firmware.bin,
at present i'chiliad left only with env LPC1768 Fault,
any thoughts?

MKS Gen_L is not a LPC1768 based controller it is a mega2560 based controller.

thank you

Delight Assistance…

I'k getting this same "timeout" error. I have an Anet A6 with an Anet v1.v lath. The board came without a bootloader then I flashed the board with a USBisp and was able to upload Marlin one.1.9. I recently purchased a RepRapDiscount full graphic smart controller, when I went in to Arduino IDE to comment everything thing in and reflash, that'southward when I become the error…

avrdude: stk500v2_ReceiveMessage(): timeout

Just like the OP states. I've tried everything! I can't wink anything to my lath, fifty-fifty my original settings. The weird thing is, I know it communicated with my lath because my original Anet 2004 LCD changed the "icons" for my TEMP read out. Another weird matter is, I originally tried uploading with my board ready as "Anet v1.0(optiboot)" because I had to originally upload a bootloader, simply the IDE always ship an error "oops brand sure you cull Arduino MEGA for your board. When I switch the board to Arduino MEGA the IDE tries to upload the firmware but comes dorsum with the "timeout" error. I've even tried flashing the firmware via the USBisp and the same happens. Luckily the printer still prints and then I just gave upwards until I can become some feedback here. I'm honestly at the point where I'g ready to just buy the Anet 12864 LCD because I still have to reconfigure the ribbons that came with the RepRapDiscount to make information technology compatible with the Anet v1.5 board. Whatever insight would exist greatly appreciated, thanks all…

Fairly sure that is a atmega1284p processor… not Arduino MEGA2560

Setting to a board of MEGA also sets the upload baud rate and protocol to
Mega.menu.cpu.atmega2560.upload.protocol=wiring
mega.menu.cpu.atmega2560.upload.speed=115200

What upload protocol and baud charge per unit your kicking loader needs depends on what bootloader you installed

a standard anet aboard needs

anet.upload.protocol=arduino
anet.upload.speed=57600

and ane with optiboot needs

aneto.upload.protocol=arduino
aneto.upload.speed=115200

These are set in boards.txt files, not related to baud rates you tin fix anywhere.

To me it sounds more like you take mucked upward the configuration.h you have to set your motherboard to BOARD_ANET_10 so in arduino IDE ready the board to Anet v1.0(optiboot)

Thanks for the reply Dust… I'm certain that somewhere along the way I deffinately mucked something up. My baud charge per unit is correct and oddly, now when I try flashing, Arduino allows me to select the Anet V1.0(optiboot) pick in "boards" and it will compile everything. However, when I click upload its now coming back with an mistake proverb, "access to COM4 is denied".

When I got that error I downloaded Repetier Host to run into if i could communicate with the printer at all. When I try to connect the host software I go the same error, "admission to COM4 port is denied". I'm not exactly sure why. And so I went into my devices and removed the printer from my figurer so I could reinstall it. After the reinstall I was able to connect to the printer through Repetier Host although I couldn't control the printer, nor wast the printer sending it's info to my computer.

I went dorsum into Arduino IDE and tried to flash again. I got the aforementioned access denied error and when I went dorsum to Repetier Host I could no longer connect my reckoner to the printer (access to COM4 is denied).

I'grand guessing that my easiest pick is to purchase a new motherboard, I wouldnt listen upgrading to the 1.7 version anyway as information technology has a fuse and the pins will work correctly with the RepRapDiscunt 12864LCD.

Access denied is simply windows being a arsehole (what it does best)

run arduino ide every bit administrator

Yup, that was the trouble. I ended upwards getting a new board anyway just for the added safety of the fuse and was having the same outcome with the V1.seven board. It came to me bricked and when I tried to upload the bootloader same thing. I ended upward bypassing the COM and just using my USBISP, but accept since gone back and run as Admin and was able to connect. Cheers for your help and time Dust, I truly appreciate it!
