Sorry, the correct entry point is NOT 0x8002000.
That's the location of the text section in the blackmagic.bin example.

Hi Marc,

That's great, good to see it's working.
I actually used from here

I tried modifying the linker script in paparazzi/sw/airborne/arch/stm32/stm32f103re_flash.ld to correct the entry point but that didn't work. The correct entry point from the black-magic docs is 0x8002000, which is also repeated in as the offset to start programming from. The blackmagicdebug makefiles have a file designed to be loaded via stm32_mem, and the makefile has the .text section relocated to 0x8002000 and the flash origin @ 0x8000000, just like the paparazzi linker file. I'm now out of Lisa's with bootloaders, but in the interests of helping others:
- Loading ap.bin directly via doesn't work
- Modifying Makefile.stm32 to include the LDFLAGS -Wl,-Ttext=0x8002000 doesn't work

I've got a jtag cable on the way, so I'm probably going to give up and switch to jtag for the time being rather than remove the diode. It's just frustrating - the bootloader is there, the programmer seems to work, we just need someone to tell us what we are doing wrong :)

Hi Gareth
(and all others with Lisa/M but without JTAG :-)

just had the same experience as you.. Blinky, upload ap.bin, End.

I think Esden is very busy with the quadshot at the moment (and on holiday). So I wanted to program the Lisa anyway...

My way is using the "traditional" serial bootloader. It´s a hack, it´s slow, but it works (just got it working some minutes ago).

In short: remove diode (usb->VIN), connect aspirin ACC_INT to GND (Boot1), Boot0 to 3,3V, Connect 3,3V FTDI to UART1 (TX/Lisa=USB-VBus).

Then change the loader path in the stm32 makefile to your directory where you put it (ok, download it before...

Set flash mode to serial in airframe file.

Power on (no longer over USB! Set jumpers correctly before)


Wait :-)

If there is greater interest, I could write something for the wiki.
Then it would also be good to adjust the path and add the loader to the repo permanently...

Hi Esden,

Could you quickly detail how to use luftboot?
I tried flashing ap.bin to a lisa/m 2.0 via, it programmed
fine but the bootloader is now stuffed and it doesn't seem to be doing
Presumably the offsets are wrong?
I'm on locm3 but all airframe files still try to upload via jtag.
