[nelsonline66]

Hi all,
a friend lend me a ds203 to try it,he don't have used it for some mouths...
i ave connect it to a usb charger and power up ok.after charging i ave just unplugged USB charger and try to power up
but got blank screen and beep.
is not recognized as disk on different computers using windows XP and windows 7,just say unrecognized usb hardware.

follow the tutorial to upgrade DFU 3.45 no more blank screen ,have asked and put the serial number but got FPGA error.
the problem this firmware are for 2.8 ,i have found a file DS203_boot(HW272) try it and got blank screen/beeping again

in all cases its not recognized usb on pc,

i can write directly to the (bios) winbond 25Q64FVSIG someone can make me a dump of the bios.

maybe its a hardware problem i have not trying to flash it before .

any help is welcome.

thanks

Here is .bin for DFU v3.10 https://www83.zippyshare.com/v/6pQlQcFx/file.html

Here is something else to try DFU_C312-SYS_B160-FPGA_V261-APP_PA1_V111_LOGO-Seeed(BC3B).hex.zip https://www83.zippyshare.com/v/8ySSwlw5/file.html

I don't have experience but I think you can upload everything with 3.3v Serial adapter and Flash_Loader_Demonstrator. Other option is load latest DFU and then use computer to copy to drive sys,app,fpga. If DSO in DFU mode shows up in computer then you only need to upload latest app and sys and fpga for hw2.72.

Btw, DFU older than 3.46C required Windows XP or 7.
