1.0.2 not working on my Mega 2560 and RAMPS.

opy01

I have multiple Mega 2560s, RAMPS and REPRAP DISCOUNT FULL GRAPHICS SMART CONTROLLERs. I can get 0.92 to load fine, but there is no TMC2130 support. I try to load 1.0.2 onto any of my boards and the LCD is just lit up and blank. When I go from 0.92 to 1.0.2 the screen locks up and never reboots on its own, I have to power cycle and then it's just a lit blank screen. I've tried changing many of the settings wondering if there is a configuration issue, but nothing helps. Is there something with 1.0.2 that I did wrong? I'm using the Arduino IDE to load the firmware. When I go back to 0.92 everything works except my steppers that use TMC2130 drivers.

Any suggestions are welcome and appreciated.

I did not notice that you can switch to production 1.0.1. That seems to be working so far. Now to get my bed level sensor working.

I compiled it for Mega/RRD Full Graphic and it worked like expected.

The sd card is using the same hardware spi that the TMC is using and 1.0.2 has new sd fat library with own spi access. That might be tge main source of the problem. I guess without explicit TMC support it is working?

It is currently working on 1.0.1 as downloaded from the site, but when it boots it says 1.0.2. My main priority at this time is getting the z probe working.

opy01

Well I figured out why 1.0.2 would not load. I had the SD card in when uploading the firmware. I removed the SD card and it works fine. I can insert the SD card and it reads fine after booting, but it will not boot with a SD card in the slot.

Hello @opy01!

I'm the guy responsible for the Trinamic support. I've just tried to reproduce this issue using an SD Card slot connected to my RAMPS board and I cannot. It works just fine for me and I can start up the drivers with an SD card plugged in and read the card just fine.

I want to understand your setup better so I can figure out what is wrong there. Can you please post your connections for the trinamic drivers. Most importantly, where have you connected the CS lines to?

Better yet, post some pictures with the board and it's connections if you can.

opy01

It has nothing to do with the drivers, its my MEGA 2560, RAMPS and reprap discount full graphics smart controller. The only reason I mentioned the drivers was 0.92 did not have support for those drivers and I needed 1.0.2 working.

When I upload firmware 1.0.2 into my board while the SD card is in the slot, the screen is just blank but lit up. As soon as I remove the SD card it reboots just fine. I have not tried just powering up the board with the SD card in it.

My other Mega 2560 and RAMPS won't load 1.0.2 at all. It will load 0.92 though. I just got another Mega 2560 in and will try it when I get a chance.

opy01

Out of the 3 working Mega 2560 boards I had, only 1 worked every time I uploaded 1.0.x. That one just died. I think either the USB burnt out or the main chip fried. Had a power surge or something.

I had a brand new Mega 2560 I just removed from the anti static bag and uploaded the firmware and the exact same thing happens where the firmware uploads but I have no display. Now both of my only working boards have no display when using 1.0.x. They both work fine with 0.92, but there is no TMC support in that version. I've tried them both on 2 different LCDs and RAMPS with the exact same results.

I'm trying to make it work and narrowing it down. On the original, if I had a SD card plugged in it would not boot, but once I pulled the SD card it booted fine then I could put the card back in and print. On the one I am currently working one I can pull the EXP2 cable and the Repetier logo comes up, but it still doesn't boot all the way. I think something is wrong with SD support on this version or on this model of display.

I just got it to boot with 1.0.2 by unplugging the EXP2 cable then plugging it back in then unplugging it and when the logo comes up I plug it back in and it boots. Its definately an SD reader issue, but I'm trying to figure out if it's the firmware or hardware since it works fine with 0.92.

I just replicated this on the second Mega 2560 board.

opy01

This is absolutely insane! Both of my RAMPS boards have back EXP2 solders. I wonder if 0.92 was not using the specific pin or maybe it did not need as much power. It's no wonder I had no issues from that one board, I must've had it in just the right spot until I fried it and had to swap it out.

opy01

Well, I thought I figured it out, but now I don't know. I resoldered every single pin. Now I'm wondering if it's a pin issue in my pins file...

opy01

I am slowly rebuilding the firmware from scratch. I appears that when I enable pin D32 for my CS pin that is what is screwing up my firmware. I have verified that PIN 32 does NOT go to any of the LDC pins on my smart adapter so I have no clue why when I unplug the EXP2 it boots up.

There is nothing for motherboard 33, RAMPS_V_1_3, that has pin 32 in it. I also just tried pins 47 and 57 that are not used anywhere else. So I'm not sure if this is a pin thing or a TMC thing.

@alexsomesan
So back to your post above, now that I know it's a TMC thing. This is all happening with just the RAMPS plugged into the Mega2560 and RRD full graphics smart controller. No stepper drivers, no temp sensors, no heater. It happens while plugged into USB or 12v. I'm not sure how my other one was even working before it got toasted.

@Repetier
Referencing your question above, it does work fine if I disable TMC support.

I did try disabling SD support while TMC support was enabled but I get the same results.

@opy01 Can you try out this version? https://github.com/alexsomesan/Repetier-Firmware/tree/improve-trinamic-init<br/>It has some improvements to the initialisation code that should make it more tolerant. I'm trying to also add log messages for the init code soon.

Let me know if that version improves anything.

opy01

I'll try anything. I have multiple boards to work with so I don't have to worry about taking my machine down... when it actually runs lol. I'll let you know how it goes tomorrow.

Thanks for your help and thanks for your patience while I work through all my little bugs. Half are user error and the rest are either cheep parts or little things like this. But I love experimenting and learning and helping out however I can.

opy01

Same results. Upload with #define DRV_TMC2130 uncommented and it will not reboot unless I jack around with the EXP2 cable unplugging it or moving it enough to break connection, but as soon as I comment out that line again and upload, it reboots and works fine.

opy01

I just borrowed an MKS board and loaded the firmware on it and it booted fine. It's something to do with the Mega 2560 and RAMPS 1.4 board combo.

alexsomesan

@opy01 Can you share the exact branding on the RAMPS, the LCD adapter and the actual LCD board that you are encountering this with?

I'm thinking to try and procure those and try to dig down into this.

opy01

I bought a couple of kits. This was the other one made in China instead of Italy.
