Wm320 board reading? #102

Closed Weanuts closed 3 years ago

Weanuts commented 5 years ago

Might someone please help with this reading? What has happened in putty? Trying to boot Nand. read board1

mefistotelis commented 5 years ago

If that's a serial interface which should display text, then either transmission parameters are wrong or your usb-to-ttl is incompatible.

Weanuts commented 5 years ago

Do not know if following proper protocol, but here goes. Was able to connect changing baud rate. I received boot me boot me """""""""" Using same setup was not able to receive any info off of nand chip after disconnect of 3.3v and BT00 and BT01. Can you please help with link to download TI utilities and u boot images. I have read your posts on (Flashing firmware on DaVinci media processors · mefistotelis/phantom-firmware-tools Wiki · GitHub), and https://phantompilots.com/threads/fixing-flash-in-dm365-chip-within-ph3-pro-gimbal.127310/ I am at a loss after these readings.

I must say that you a genius when I read a few of your hundreds, probably thousands of posts.

thank you for help

Can you recommend which Nand flash chip is needed on my board? 4YE12 NQ283 (MT29F2G08ABAEAH4) or 4UF12 NW361 (MT29F1G08ABAEAH4) My board is a P01069.07

thank you again

mefistotelis commented 5 years ago

which Nand flash chip is needed on my board?

Look at board pictures, and check which of them is missing on Ph3 Advanced board - DM36x only exists in Pro.

Can you please help with link to download TI utilities and u boot images.

TI utilities are on TI site, which is linked to here: https://github.com/o-gs/dji-firmware-tools/wiki/Flashing-firmware-on-DaVinci-media-processors

Modules from P3X firmware - you can just extract from official firmware releases. Here is a tool for downloading firmwares: https://github.com/cs2000/DankDroneDownloader Start the extraction with dji_xv4_fwcon.py, then read wiki to figure out what to do next.

Weanuts commented 5 years ago

I am a but head. I did not see the third choice, My craft is a DJI phantom 3 professional. My board is a P01069.07 I believe I need a MXIC X154009 MX30LF2G18AC-XKI 8C149000

(63-ball 11x9 VFBGA | 3V SLC 2GBit NAND Flash memory; contains programming for Ambarella A9 -- | --)

I am missing on screen play. (fpv) 08 00 15 00 device not detected. Could you please tell me if I am correct, this time?

thanks again John

mefistotelis commented 5 years ago

Ambarella writes on SD-card and forwads FPV signal to DaVinci. If SD-card write works fine, then Ambarella works correctly. So - no, what you wrote is not correct.

Weanuts commented 5 years ago

SD-card receives and is written to, movies and stills that can be seen on my computer. So in short, what am I lacking (other than experience) to achieve an on screen picture on my Ipad?

thank you once again for taking the time to instruct me

mefistotelis commented 5 years ago

You know the issue is with m0800, right? Look here; on the left you have chips used for each module, then module marking: https://github.com/o-gs/dji-firmware-tools/wiki/WM320-Gimbal-top-board#programming

So your NAND model is on the left, and you can click module marking to get more info on the module which got damaged.

Weanuts commented 5 years ago

Correct, m0800 is upset. How do I know if Loading kernel via USB stick is possible, on my board? If so, can I use a USB 2.0 Type A Female To Micro B Male Adapter to load kerne (?)l onto Wm320 board via usb stick?

I again much appreciate your help with my endeavor.

Seasons greetings, John

mefistotelis commented 5 years ago

How do I know if Loading kernel via USB stick is possible, on my board?

Try it and you'll know.

can I use a USB 2.0 Type A Female To Micro B Male Adapter to load kerne (?)l onto Wm320 board via usb stick?

So to simplify - you want to ask whether you can use micro-USB port soldered on the top board. The answer is - you probably can, but not in the way you think; that port is connected to an USB Switch which can be switched to DaVinci. But normally, it is switched to Ambarella.

If you can figure out how to toggle the switch, then you should be able to use that USB port. I never tried that.

Weanuts commented 5 years ago

Thank you for answer. The power was out here yesterday for 12 hours so I was late getting back to you. I will solder to board and update you.

thank you again John

Weanuts commented 5 years ago

Ok, I have everything ready, pin 1 and 2 from ofdm to female usb connecter, but, for life of me, I cannot find ("After the pad is connected, use TI utilities on connected PC to flash your new image:") TI utilities ???? I found TI connect, but!

mefistotelis commented 5 years ago

It was explained two paragraphs later; I made it more connected and better explained now.

Weanuts commented 5 years ago

capture2 Well after a lot more reading, I finally started to re flash but, I am back at a stalemate. I tried numerous times to re flash but I get the results as the enclosed capture. Can I continue with different flash or do I need a new chip?

mefistotelis commented 5 years ago

The message says interfacing error, not NAND write error.

Make sure DaVinci gets enough power.

Weanuts commented 5 years ago

Can I use an auxiliary power source to supply 5v power to board?

thank you

mefistotelis commented 5 years ago

That is exactly what I suggested.

"File ubl1.img is not present"

Weanuts commented 5 years ago

mefistotelis, I was able to write to nand but not sure if I am "done" or just starting. Here is a printout of the operation. Your help is extremely appreciated. Success or.txt

mefistotelis commented 5 years ago

Looks ok to me. Remove the BOOT0 wire and check what serial interface shows during boot.

I used your log as example in the wiki.

Weanuts commented 5 years ago

Removed wire, and Using Putty I was able to receive this "LONG" message. And of course being the geek that I am, not sure what It all means. Enclosed file After Nand reflash.txt

priegor commented 5 years ago

If you power on board without OFDM module and Gimbal, log seems ok. Now need fix 8fps issue. Follow this post Read "UPDATE - Regarding 8 FPS FPV after NAND replace:"

mefistotelis commented 5 years ago

This issue is described on the wiki:

Loading from nand0, offset 0x4a0000
** Unknown image type
Wrong Image Format for bootm command
ERROR: can't get kernel image!

Beyond kernel - the Linux seem to be booting ok, so that's the last thing you need to fix.

Weanuts commented 5 years ago

mefistotelis

So can I, try this??

Home/DJI Firmwares/Firmware m0800/

"Flashing firmware via SD card",

"By official package in camera" ??

mefistotelis commented 5 years ago

Hm, I was always flashing the kernel "by hand" (I mean, using YModem and then dd), and I referred to this wiki: https://github.com/o-gs/dji-firmware-tools/wiki/Flashing-firmware-on-DaVinci-media-processors

But what you suggest might actually work. The DaVinci Linux is booting, so it should be able to perform the update correctly.

Try it. Either with whole package, or only the module 0800 in camera. I'm pretty sure it will work.

Weanuts commented 5 years ago

SUCCESS:

Ok I tried it with the whole package. It worked. I have video transmission to my Ipad. P3X_FW_LOG_AB.txt P3X_FW_RESULT_AB.txt

1/ Can you tell me from files if I have to change frame rate? (8fps or greater>) 2/ Your write up on leaving craft for a long period of time without usage, could this have caused my problem of "No video transmission", 3/ or excessive heat caused by upgrades or downgrades.

This craft came to me broken up internally. It had 4 battery charges at the time. It now has 27 recharges, and I have flown it a maximum of 30 minutes. The remainder of the recharges were consumed by trying repair the software.

I must say that for YOUR help and others on this forum and the large amount of info found on the web I will forever indebted.

thank you mefistotelis

mefistotelis commented 5 years ago

1/ Can you tell me from files if I have to change frame rate? (8fps or greater>)

If you see video normally, then you don't have the issue. Get the drone to a well lit location and wave your hand in front of it to check.

2/ Your write up on leaving craft for a long period of time without usage, could this have caused my problem of "No video transmission",

Yes.

3/ or excessive heat caused by upgrades or downgrades.

Yes, that could also be the cause.

Weanuts commented 5 years ago

I want t thank you again for all your help. I still have to break down the unit to work on the Wm320 board, to remove remaining jumpers and install new heat absorbing pads, before I go for my first real flight. Have a great one.
