upload does not work at all for STM32F407ZET6 on linux 64bit

[uzi18]

I'm trying to use this bootloader but upload always stops on sending first 1024bytes:

> Searching for 1209:BEBA HID device...
#
> 1209:BEBA device is found !
> Sending <reset pages> command...
> Flashing firmware...
. 1024 Bytes
^C

any idea what is wrong?

Hello uzi18. What OS do you use (mint, ubuntu, etc) ?

[uzi18]

it is nothing you know - PLD Linux, but I dont think it is OS problem.
need to debug if any data are realy received by hid bootloader

also found bug in cli program but this is for another issue

[uzi18]

did some checks, program is waiting for acknowledgement from bootloader, about 1kB already flashed

page reset raport is sent by hid-flash and received by bootloader - this works

next step: hid-flash sends 1024B block but not receive info to send next block

@Serasidis any idea?

[Serasidis]

@uzi18 I suppose:

1. you use the Arduino_STM32 repository (...arduino_folder/hardware/Arduino_STM32)
2. You have applied the patch
3. You have the BOOT-0 and BOOT-1 pins connected to the GND

I have successfully tested the HID-BL 2.0 to 2 Diymore STM32F4 Discovery board (407VGT6) and ArchMAX 1.1 (407VET6)

Which STM32F4 board do you use ?

[uzi18]

this board: https://www.solidrop.net/product/stm32f407zet6-development-board-m4-stm32f4-core-board-arm-development-board-cortex-m4.html

have bypassed any check to go into bootloader flash mode directly, but it does not work as I expected.
sending reports from cpu to os hid-flash works but some data packets from hid-flash are lost.
need to check on another module or/and if usb/cpu is correctly soldered.

[uzi18]

I think it is needed to add some sync every 64B received, if timeout reached resend it one more time.

[uzi18]

@Serasidis changed board and have some progress here, will test it one more time without my modifications. Also need to find what is wrong with other board.

[Serasidis]

@uzi18 is there any progress ?

[BennehBoy]

@Serasidis shout if this needs a separate issue, but on Black407VET6 (and presumably f4xx) first upload works fine, but upon system reset the board is in perpetual bootloader until the reset key is hit, am I doing something wrong?

[BennehBoy]

Oops - had BOOT0 set high, removed jumper and now working.

Have you tested against a blackZET6 board?

[uzi18]

Will try later and give you feedback

[BennehBoy]

Actually I think BOOT0 may be a red herring, it only occasionally goes directly to sketch execution - perhaps due to it floating?

[BennehBoy]

OK, so got to the root of the issue, the code, although it has a comment in saying 407VET6, has the incorrect GPIO's set for BOOT1 & the LED.

After setting this up correctly for Black407VET6 & ZET6, with BOOT1 high & BOOT0 low, both cards boot straight into the sketch. Sorry for all the noise in here, but got there in the end.

[uzi18]

@BennehBoy did you get ZET6?

[BennehBoy]

@uzi18 Yes. Tested and working with my PR over at STM's core -> stm32duino/Arduino_Core_STM32#415 It's still WIP however, needs tweaking for @Serasidis latest changes (BL 3.0 compliance).
