Can u give me the link plz? 

WARNING! What works for one Axpert Max 8kW does not necessarily work for another!

Since Gilberto asked for the links to the firmware used by Sharkut, and Gilberto is in a world of trouble already, I provide the links:

"92.05", which is factory main DSP firmware version 92.04 with Georg's patches for 200 V minimum PV voltage:

Always giving me this

I presume that you have done firmware updates before, so you know that COM3 is for your compatible USB to serial adapter.

So it looks like either you don't have enough patience to get the timing just right, or the firmware crashes so badly that it won't start a firmware update.

Thanks! I have tried several ways. Turning on and pressing update ou letting it pass some seconds etc. No success

It looks like you'll need the new display, or a JTAG programmer.

With the JTAG, you will need to know if you have a suitable bootloader. If you're interested in the JTAG route, the next thing would be to open up your display and find out what exact processor is in there. If it's the GigaDevice brand, then you will need to have a bootloader extracted from someone else's display, via JTAG.

So it's not trivial, but not super hard either.

[ Edit: GigaData → GigaDevice ]

Ok. I will open it up to see

Reading this forum, seems like updating the MAX firmware is not a good idea!

What jtag should I buy? The supplier is really bad communication so it takes lots of time

This one works?

Yes. But it would be really helpful to see the number on the top line.

Any chance you could take another photo without the WiFi board in the way of the rest of the part number?

Edit: And you have the GigaDevice part, which complicates things a little. But I guess that's why you got into trouble in the first place.

It's impossible to tell without a link or at least a brand name. But "Altium" suggests FPGA to me; you need an ARM (formerly Acorn Risc Machine) JTAG device, i.e. one intended for use with ARM chips, and comes with software that knows how to access the JTAG port of ARM compatible chips. JTAG is a very low level protocol; it accesses machine registers directly, so that's why it has to be specific to the family of processors. Different processor families have completely different registers, even if you consider only those registers needed to access memory and perform flash programming functions.

Perhaps try to find the same one as in the "boom!" post. Forgive me if that is the same one. It looks similar from memory.

Edit: see also the post below. In it there is a link to the ST-LINK/V2 device that the cheapies are emulating. I'll try to find a link you can use. Busy right this second.

Edit 2: With the exact part number, I can also hopefully tell if you need a GigaDevice specific JTAG programmer, or if a general ARM JTAG programmer would do.

That one is DSP compatible, so it would work for the DSP (hopefully we don't have to go that far). TI do make some ARM chips, but they seem to be a different family (A8 versus M3 V7). So I'd say no, without looking into it too deeply.

You want one that is compatible with the ST-LINK/V2. This one seems ridiculously cheap:

Actually, this one seems more respectable, and is similarly priced (except expensive but fast postage):

Seems like GD32F105

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!

 

Why in hardware error do update? Error 52 "low bus voltage" is from dc-dc source First need repair hardware inverter.

Brilliant! So it's the GD32F105VCT6. It seems to be pin compatible with the ST32F107VCT6. I'm guessing that you can find either the '105 or the '107 part from either manufacturer on these boards; the only difference between 105 and 107 seems to be that in the 107, one of the I²C ports is dedicated to an ethernet port. I'd say that the ethernet functionality is unused, so that the 105 and 107 would be essentially interchangeable.

Now I need to wade through the various datasheets to try and figure out if they're flash and JTAG compatible. Edit: so far, unfortunately, the answer seems to be no, unless you buy one of the much more expensive models, like the Black Magic Probe (to be confirmed).

Now you are speaking Chinese to me😂 so I will not be able to do anything? What bad luck! I can’t get a new control panel as the supplier does not respond to emails.

OK, then JTAG is your friend.

It looks like ST-LINK is the original JTAG emulator for ST ARM devices, and GigaDevice makes a similar thing called GDLink. So you probably want inexpensive devices based on GDLink. This seems to be one such:

https://www.aliexpress.com/item/1005004576805005.html

It's totally not clear to me what software you get with it, or what you are supposed to find yourself and download. It doesn't sound like it's tested on a whole lot of GigaDevice chips, but for the purposes of flash programming, I'm guessing that it should be good enough.

You will need some link wires as per the Boom! post; take note of the one with GND, DIO, CLK, and 3V3 (partly obscured) in it, and locate that 5-pin connector on your display board. Make sure you get the right orientation (observe the notches). Or you could make up a custom connector with the 10-pin header at one end, and a suitable JST plug at the other end; you might be able to make it from two off-the-shelf cables.

It might be worth downloading the manual before committing to a purchase, so see if you (perhaps with the forum's help) can figure out what you need to do. If you don't like this one, just do another search for GDLink and GigaDevice.

There is possibly the bootloader problem. But it seems to me that your bootloader will still be there; if necessary you could read it out (I recommend that in case you accidentally do a bulk erase). You should be able to erase and flash only the non-bootloader flash segments. That's assuming that they haven't protected the firmware as yet.

Basically, it looks pretty doable.
