I'm flashing my Portenta H7 with STM32CubeIDE through a Portenta Breakout Board via an ST Link v2 (the real ST one, not a clone). The JTAG pins on the breakout board are 2x10 1.27 mm pitch and the ST Link has 2x10 2.54 mm pitch pins. The above board is ideal (I found it here on this post) but I'm looking for some alternatives so that I don't have to wait 5 weeks for (Amazon ).
Hey Arduino people! I'm having a heck of a time finding 2x10 2.54 mm pitch to 2x10 1.27 mm pitch adapters for that JTAG connector on the breakout board. Plenty of 2x10 2.54 mm pitch to 2x5 1.27 mm pitch adapters but I need to physically cut the plastic ends off of the 2x5 because those plastic ends stop you from plugging into the 2x10 JTAG connector on the board.
Any hints on flashing the H7 from STM32CubeIDE or STM32CubeProgrammer?
Also, where can I get the H7 .bin bootloader file (is it's loaded size different from the standard STM32H747XI bootloader)? Do I need to adjust the applications start address?
Bootloader: 0x08000000 – This is usually reserved for the bootloader.
Application: 0x08004000 or higher, depending on the size of the bootloader – This is a typical starting address for the application if the bootloader occupies the first 16KB.
Take a closer look at EmilyJane's response, it has a picture showing how to make one and that can be done in a few days including PCB. Try JLPCB.com, they can even supply parts.
Thanks! I did not know the v3 came with the connectors (my v2 did not). Unfortunately, I can't drop another $59.89.
It's looking like my best option is waiting 5 weeks for the Amazon connector I linked to in my original post at $13.55. Though I could probably get it sooner from Arduino (the exact same connector) but they want $40.92 for it!
In your nearest city, look for engineering companies in the field of tech (rectanguloid building, two stories tall, two hallways deep and ten offices long). Many will design their own circuit boards and program their own chips. Ask for their production lab. They will know what you want, where to get it. And... they might have one collecting dust.
A bit late, but I happened to be looking at my ST-Link v3 and I noticed that I have one of those adapters in the box with it (probably for when I was using a v2) and it's made by Adafruit.
