problem

I use OpenOCD r115 and str736f

when I write the internal flash there is an error, but it seems that it goes ahead

the error is:

Error:   str7x.c:325 str7x_erase(): BUG: str7x_info->sector_bank[i] neither 0 nor 1 (262161)
Error:   str7x.c:325 str7x_erase(): BUG: str7x_info->sector_bank[i] neither 0 nor 1 (524597)

is it a problem?

thanks
