STM32 flasher problem

[teevee]

Hello I want to flash my Gotek drive and I haven’t been available to get the "device decteded" yet and only shows “Link up”. So I canoot flash my drive yet.

Picture of my connections:


Thoughts:
Using the solder pads and pin header, should not make any differences, as they are the same? (Or maybe not)
When I look closer at the "solder pads" and "pin header", then I can see:
• Called RX at the pin-header, but RXD on the solder pad.
• Called TX at the pin-header, but TXD on the solder pad.
• GND is GND, not matter if you take it from pin-head or solder pad.
• “5v solder pad” vs “VCC pin-head”, when the jumper is set correctly on 3,3v, then it won’t matter either?

I also saw another topic here on the forum, where a user had a similar problem and he only switched the USB adapter. I used the same USB interface adapter, which is mentioned here:

I'd double-check that your 5v source is giving off 5v, and then check that the 5v is making it to the 5v pad on the Gotek (if you don't want to solder directly to the pad).

I got one-step a head after I updated the USB driver on my computer, but the programming does not get very far before it freezes.

What is then wrong?

I tried a few times and never manage to get higher than 15/100:

I found the error and its now flashed:
The problem is the STM32_SerialBridge is not compatible with 64 bit Windows 7, so I found my old Windows 7 32 bit laptop, which worked after 2 tries
• It had a sync error at first try, but worked fully after. (It makes some sync something around 50/100)

Hmm, I have a similar problem, I have win7 64bit, and I can flash the cortex software without problems using the flash loader, but when I try to flash hxc with the serial bridge it stop on 49/100 every time..

Yesterday I tried with a laptop running Win7 32bit.

flash demo with cortex works fine, I can program it any number of times.

However, with the serial bridge I can connect to the gotek and the server, but if I click "program" nothing happens.

Hi.
I use Win7 64b and an Arduno Uno (5v) to flash Gotek with Cortex firmware.

It works with STMFlashLoader Demo.exe but i need to use 2400 bauds


I flashed 2 Gotek like this and a lot of time (Just to try).

BUT, i can't flash Gotek with SecSerialBridge.exe !



What can i do or how can i have my money back ?

You can always write to Jean and find a solution (Or use Paypal resolution center, if you paid with paypal)

On this particular FTDI232R adapter the jumper switches not only TTL standard of Rx and Tx lines, but also the Vcc. So when you set the jumper for 3.3V you can't use the Vcc line from adapter to power up the Gotek. You can either set the adapter to 5V, because as far as I know the STM32 UART pins are 5V tolerant, or use an external 5V power supply for Gotek. It requires only 5V on power connector, 12V is not required (as for most mechanical floppy disk drives).
