Re: Connection problem with eBay board

i'm doing nothing else. it will run using the USB to the rusefi console. There is no need for a bootloader and im using new blank chips. Ahh, I was under the impression you needed the USB BL to talk to TS - I guess when you don't know anything you say the wrong thing -. So just load rus with the ST...

Re: Connection problem with eBay board

It must be the same bootloader as you are using to get native USB on your custom board because it's the same STM32F407VG chip on all the boards. Sorry for not looking into it - when you are old confusion is demotivating :? - but where did you get the bootloader from.

Thanks

Re: Connection problem with eBay board

Hey NickZ, did you get the little boards running.

And what bootloader did you use to flash it to get the USB working.

Re: Connection problem with eBay board

I was watching Blue Pill bootloader vids last week and it comes with the serial bootloader, and if you want to use the USB you need to load the USB bootloader first. I assume these board are the same. This is the old one. https://youtu.be/wGbiT6IxGP0 This is the updated one. https://youtu.be/Myon8H1...

Re: Connection problem with eBay board

The Discovery uses the VG STM32F407VG, so that chip should be more compatible - I don't know about ZE, but the VE has less memory -.

NickZ got his running.

Re: Frankenso - ECU shield compatible with OEM case / official

The $6 chip from Ali is a VG and looks real - it should be a goer ;) -, but if you get the on-board STM32 working on the FK can you easily disable it and go back to the Discovery board.

I'm not good at that stuff, and I don't have a board, but I might do some reading tomorrow.
Does the writing and font on the chip look like this genuine chip. Does the indent top right have that broken centre.

Are you sure about the 28MHz crystal. I found this dwg, if this is the correct one, and there is a 2 in front of the 8M. But that looks like pin 2 of the crystal. http://dubstylee.net/v/wp-content/uploads/2017/08/DIY-More-STM32F407VGT6.png It's from this post. https://community.st.com/s/question/0D5...

That last vid took a bit of time. I don't know how well Frankenso kits sell, but after making one it seems a bit too much trouble.

I'm feeding the FK with 12V, and I'm getting 5V at the reg, but the other 5V points on the PCB are only getting 0.4V. Are there any links that have to be made to get the 5V to the internal PWR plane.

Re: Frankenso - ECU shield compatible with OEM case / official

I was just thinking that the pad is 1.4mm, and a 1206 is 1.5mm, so I thought it would be wise to link them to the 0.070" pins on the Denso connector. If it does 2 High-Z with a single 0805 it's probably not necessary. 8-)

When you get the Frankenso pre made, can you see red dots of glue under the 0805s on the underside. I hear that 0603 and smaller will stay on the underside without glue with a 2 oven process - oven solder bottom side parts and re oven for the top side parts -, due to the solder surface tension, but ...

Re: Snap on programming header like the OEM's do

If it's that 6 pin header row in the middle of the Frankenso, it's going to have to be a robust 3D print to clamp 80mm away on it's own. One of those cheap plastic clamps in my video with more reach would make it easier. https://rusefi.com/images/Frankenso/frankenso_0_5_assembled_as_recieved_front.j...

Re: Snap on programming header like the OEM's do

Seams like they do make a 0.5mm pogo, so I suppose you could just slide it in a female header if that is what is on the programmer. Other wise it's a PCB breakout with pogo on one end and the IDE connector on the other. 0.5mm and 0.68mm pogos. https://www.ebay.com.au/itm/100-Pcs-Spring-Test-Probe-Po...
