Firmware restart while refreshing DWC and pausing

Veti

@felek said in Firmware restart while refreshing DWC and pausing:

Supply voltage: min 1.7, current 1.7, max 1.8, under voltage events: 0, over voltage events: 0, power good: no

how are you powering the duet?

felek

@Veti I test setup on my desk

Veti

have you tested with a real power supply?

also
M350 X32 Y32 Z32 E16 I1 ; configure microstepping with interpolation
this is not valid for the duet 2. interpolation only works at x16

felek

@Veti I removed I1 from config.g

I tested on 3d printer and It still ocurrs

Simulation works fine on 2.05.1 firmware, however there is issue when I want to load DWC (or refres).

I tried to print but duet rebooted

AFAIK when duet has issue with external SD card it should indicate error like: "Cannot read file, error code X"

Please post the GCode file that caused the reset when you simulated it.

felek

@dc42 This file is quite big
https://www.dropbox.com/s/twebf0ajjvn0bdd/moon6inches.gcode?dl=0

felek

@dc42 I was digging in the firmware in order to find solution. I have no idea why Network task cannot Give SD0 mutex when external SD is simulating. It is happen when refresh DWC. Firmware want to send all files to the browser and it got stuck in void NetworkResponder::SendData()

I also don't have old releases duet PCB with JTAG socket so I'm not able to use debugger.

@Veti said in Firmware restart while refreshing DWC and pausing:

M350 X32 Y32 Z32 E16 I1

@felek Rather than remove the I1 to stop the interpolation, better to use x16 microstepping with interpolation enabled to begin with.

@felek said in Firmware restart while refreshing DWC and pausing:

PanelDue(3.2.9)

Would you be able to test again with PanelDue 1.24?

felek

@Phaedrux Ok, I changed microstepping to 16 and enabled interpolation.

@felek said in Firmware restart while refreshing DWC and pausing:

@dc42 This file is quite big
https://www.dropbox.com/s/twebf0ajjvn0bdd/moon6inches.gcode?dl=0

Wow, 106Mb gcode file. I'll try simulating it myself.

Phaedrux

I was able to simulate that gcode file on a Duet2 with fw 3.2 on the internal SD card without error. I don't have the ribbon cable connected for the PanelDue SD card slot, so I can't test that.

You could try reducing the baud rate on the PanelDue and in your M575 P1 B57600 S1 command to see if that improves it.

felek

@Phaedrux internal SD card works great but external SD has issues.

PanelDue is not problem in this case.

I enabled debugPrint in CoreNG and M111 S1 P10 (Storage) in order to find bug.

This log below is while simulating and refreshing DWC (sd_mmc errors)

I figured out that ctrl_access.c is vulnerable and two task might have access in the same time so there can be a race condition.

I also noticed that there is support for FreeRTOS but is disabled by default. I enabled FreeRTOS from FreeRTOS project and now it works flawlessly.

I'm testing this solution on my desk now, but I looks promising.
Now I can simulating and refreshing in the same time and I works stable. I can even upload files on internal SD card during simulating from external SD card - it takes a bit longer but it is still stable.

I did this modyfication on 2.05 firmware.

I spotted a week or two ago that the Atmel/Microchip SD card stack shares data across multiple devices (i.e. HSMCI and SPI) and flagged this for investigation. So yes, I do think there is likely to be an issue with concurrent access to the external and on-board SD card. My preference is to stop using shared data, because there is already a per-volume mutex, and I'd prefer that using the external SD card for something didn't slow down the internal one. I'll schedule this for implementation in firmware 3.3.

felek

@dc42 Okey, It sounds great.
So what do you prefer? Should I write some bypass (just omit ctrl_access.c) for this library and use direct fuctions between FatFS and HSMCI/SPI?
In this way I don't need to use extra mutex and internal SD card won't slow down.

Do you see any dangerous?
Are you going to implement this only for 3.3?

dc42

I think the problem is the static variables in sd_mmc.c:

//! SD/MMC card list
//DC added __nocache for SAME70 because 'csd' is read by DMA
static __nocache struct sd_mmc_card sd_mmc_cards[SD_MMC_MEM_CNT];

//! Index of current slot selected
static uint8_t sd_mmc_slot_sel;
//! Pointer on current slot selected
static struct sd_mmc_card *sd_mmc_card;
//! Number of block to read or write on the current transfer
static uint16_t sd_mmc_nb_block_to_tranfer = 0;
//! Number of block remaining to read or write on the current transfer
static uint16_t sd_mmc_nb_block_remaining = 0;

The first one should be OK because there is one entry per SD card, but the other four are not, assuming they are used for both HSMCI and SPI transfers. So I think that sd_mmc_slot_sel needs to be passed around as a parameter, then the second one replaced by indexing into sd_mmc_cards (i.e. initialise a local sd_mmc_card variable at the start of each function that uses it), then the other two can be turned into arrays indexed by slot (strictly speaking, one element per channel would be enough, but one per slot is simpler).

I will probably only implement it for 3.3, although it's looking likely that there will be a 3.2.1, so the fix may get back-ported to that if it is simple enough.

@dc42
Thanks for the clue!

Finally I've ported @wilriker changes to CoreNG in 2.05.1 firmware and it is working!
I tested it on my desk and it works pretty well. I'm going to start testing that solution on my printers.
