November 7, 20223 yr Hello everyone! I am having trouble with my inverter. In tha last few days i installed a battery but the inverter was always giving me a 52 error code. So after seeing the paramaters were ok i decided to upgrade the firmware but it bricked my inverter. Now i have the panel without any liht and does not turn on. The inverter has a red light on the rgb. Only hear the fans working at low speed. Can someone help me with this issue? Thanks!
November 8, 20223 yr * Did you update display firmware or main firmware? * What was the original firmware version? * What version did you update it to?

I think I updated the firmware 1st but it gave me error 32. After that I updated the mru and that is when the panel tuned black with no response

November 8, 20223 yr 6 hours ago, Gilberto said: I tried to update with 90.06 Presuming that you updated from 46.05 to 90.06, I can't see why there is a problem. I don't have any 46.xx firmware, but I'm guessing that they are the 8 kW versions of 45.xx firmware, which are 7.2 kW firmware. They both have BDR96 reflash commands, suggesting that they are designed for the exact same DSP variant (probably the TMS320F2809). I no longer recommend that anyone updates Axpert Max firmware unless the major version numbers (the two digits before the dot) are the same between the existing and update firmware. At least until some clarity emerges. It appears that Voltronic have made some hardware changes, possibly necessitated by part availability, and failed to protect against bricking by changing reflash commands. I note that the TMS320F2809 datasheet mentions a suggested replacement part that costs about 70% less. 5 hours ago, Gilberto said: Anybody can help me? I wish I knew what to do. You may need to use a JTAG programmer to reflash the display firmware, or get a new display. It might be possible to update the main firmware once the display is sorted, or it may be necessary to bypass the display, using an adapter cable. I have documented how to do this on an AEVA page. Sorry, after 2am here.

I'm starting to believe that the leading 1 is now very significant; if you update to firmware with a different hundreds digit, this seems to lead to bricking the display. Voltronic really should have precautions against this. It seems that it's no longer the case that updating to the "latest" firmware is a good and recommended thing. It's no longer totally clear what version is latest, and there are compatibility hazards. Quote What is the secondary cpu firmware? Usually, that's the firmware in the display. It handles most of the commands, though it has to regularly poll the DSP for up-to-date data. It also handles communications with the battery BMS, if present. Plus of course it refreshes the actual display, polls the buttons, and so on. It also has some USB library code for updating main DSP firmware via a USB stick, saving and restoring settings to USB stick, and so on. There is also firmware for the wireless interface, and some models have a fourth firmware for the Solar Charge Controller. MAXs do not have this fourth firmware. 3 hours ago, Gilberto said: where can I buy a new display? I think the safest way is via your supplier, you know, the one that has been so helpful so far. The problem is that you need the exact right one; there are at least two main types (one for King/VM III, one for MKS III and possibly also MAX, there is probably a third one for MKS IV and/or VM IV. I don't know if your can update firmware from one series to the others, or if there are any differences in display hardware. Then there are possibly other displays for the on-grid models. Your supplier should hopefully be able to get the right one, perhaps with suitable firmware for your inverter already pre-loaded.

I thought upgrading my firmware would correct things and just made it worse. I have already mailed the supplier but these guys take forever to reply to emails. Meanwhile what can I try to revive the control panel?

November 9, 20223 yr I also switch from 112.14 to 12.21 display firmware and same red light on the rgb but no fan issue and everything is working correctly but no response from rgb led bar anymore even with cold restart.

November 9, 20223 yr no black screen, screen remain with previous display and reboot after the update in my memories The only thing I've done before is to update DSP with specific firmware with BDR96 reflash command (ArenavINV Reflash tool) version 92.04 from Voltronic

Here is the "Boom!" post; it's about the non-removable display, but I can't see why the exact same thing would not work for the removable displays: In in you will find details of the JTAG device a fellow forum member used successfully. Hopefully the GigaDevice chip found in some displays is compatible enough to use the same JTAG device and software. [ Edit: GigaData -> GigaDevice ] Edited December 3, 20223 yr by Coulomb
November 9, 20223 yr 6 hours ago, Gilberto said: Meanwhile what can I try to revive the control panel? You could try to update with a 112.xx firmware. As with a bricked inverter, you will be running blind, but there is a chance that the bootstrap loader is running, or alternatively enough of the existing firmware works to enable a firmware update, even though the display isn't updated or even lit. Unfortunately, I only give this a 10% chance of success. You might have to try many times, changing the timing between starting the display and pressing Update MCU on the reflash tool. Good luck! Warning for other readers: do not use this display firmware unless your display already has firmware version 112.xx, as reported by monitoring software (you can't tell the difference between version 112.xx and 12.xx from the display itself).

Quote I also switch from 112.14 to 12.21 display firmware Wow. According to my latest theory, this should not be possible. Though maybe 12.21 is able to accommodate the two different brands of MCU chip. Or maybe I still just don't understand what's going on. What you have done seems very important, and may be able to save others from bricking, and possibly able to recover. If you can remember, can you please post step by step what order you updated, and whether the display was working after each step? @Gilberto, if 112.19 doesn't unbrick your display, you might consider trying 12.21 as a last resort.

Its actually a standard FT245(ftdi) frontend with backend cpld. But its vid/pid and ft245 requirement will probably not find its way in stm, nxp drivers etc. If the OP can entertain openocd, its an option.

Yes sorry it's a mistake, I totally agree with you. I will give the procedure I used later this evening
November 9, 20223 yr Previously I tried update with 90.06 (modified 200V MPPT) with ReflashXTool and display was showing UPG yes but return to main screen after 3 seconds and nothing else happened So after I update my DSP from 72.03 to 92.05 (modified version with MPPT 200V) with ArenaINVFlash tool I follow the file included in archive : MAX DSP 28066 Firmware Upgrade SOP via RS232.pdf My inverter was power ON with AC grid, no consumption at all and PV disconnected Connection of RS232 cable (delivered with inverter) and USB adapter, Opening ArenaINVFlash tool and click Update after checking COM port is OK Same as file said UPG Yes was displayed on and firmware update start with Fan at maximum speed 6 minutes after all was done and it return to main screen with ac out reconnected After that I use update to 12.21 on the forum too Click on update MCU after checking COM port is ok The Update start and AC out wasn't disabled. the update was slower than DSP. The panel screen seem freeze to last display during update but no blank or black screen After update it simply return to main screen. That's all so nothing special. The only thing that doesn't work anymore is the rgb led bar. It remain unresponsive showing very little red light. All other is working correctly including WiFi, USB/RS232 commands
