Hello,

The STR75x bootloader can not be deleted nor programmed by User or by any

programming tool in the Market. This can be done only in STMicroelectronics.

For sure, you have something wrong in your configuration,

Could you please check your Boot mode and if you are booting from

the right SystemMemory Mode. For more details you can refer to

''AN2430 : STR75x SystemMemory boot mode''

With best regards,

Rave

Hi,

it is very strange... I set BOOT0 = 1 (Vcc) , BOOT1 = 0 (GND) , GPIO0.4 = 0 (Gnd) and after RESET I send 0x7F to comport0 . I have to get back 0x75 but don't get any characters.I am using Keil demo board.

I'm having this same identical problem on an IAR STR750-SK rev B evaluation board, although I encountered it with a virgin board (no chance of accidentally erasing anything.)

My STR750 Chip says:

STR750FV2T6

Z

22 024 VG

MLT 22 630

Which is identical to the previous posters, except I think they may have misread a ''G'' as a ''6''...

Hi all,

Yes, all the starter kits from IAR,Keil, Hitex, Raisonnance and ST

already you are using have an early version of silicon that does not contain the bootloader as described in the Application Note.

You have to contact ST Sales to get the new samples shipped from the begining of September when the STR750 product is launched and try to rework the chip in your board.

With best regards :)

Hi All,

Please find the answer to these questions in the A.N2430 ''STR75x SystemMemory boot mode''. There is a detailed section for the bootloader availability on the devices. I attached the A.N , also available on the web site.

With Best Regards,

At this time is there any Win PC tool for STR75x flash programming through its system memory bootloader? Or shall I make it by myself?

Best Regards
