DSO Bootloader for 2M and 8M versions

[m.schink]

Hi all

Does anyone have the images or better the source files for the bootloader (3.11C / 3.12C) ?
If i want to replace the flash from 2M to the bigger 8M part, i have to replace the loader right ?

thank you,
mike

I don’t think the bootloader cares about the filesystem (external) flash.

There is some magic identification bytes in the MCU flash somewhere, those you need to change.

Hi Does anyone have a link for the bootloader for the DSO quad HW v2.72

I think I have corrupted the bootloader see:
github /PetteriAimonen/AlterBIOS/issues/2

I was trying to patch the SYS_B160.HEX firmware file using your AlterBIOS to get around the file corruptions which keep on happening when I try to save data from QuadPAWN aps and then from the PA1_V110.HEX (standard oscilloscope) App. It booted and I thought everything was good. Until I tried to get an App to write to disk. Now I just get a white screen (WSOD) and am unable to get access to the device through usb

    hub 2-1:1.0: unable to enumerate USB device on port 7

I cant even get to the flashing page. I can only assume that the firmware has accidentally corrupted its self and the boot loader!!! :’( Why isn’t that memory area write protected!!!

The device will switch on to a white screen, there are no beeps, and holding down the >|| button dos not result in the bootloader page, just white screen. So I think i need to use the UART serial to reflash the bootloader with the stm32flash or stm32loader program.

So to reiterate, does anyone have a copy of the bootloader for HW v2.72 or 2.7? will the v2.6 bootloader (i have a copy of this from PetteriAimonen) still work on v2.72 HW given that this has 8M flash as oposed to 2M, dose anyone have v2.72 HW and are they prepaired to make a copy of their bootloader using stm32flash or stm32loader.

Thanks in advance and All the best
