Bootloader for STM3210E-EVAL?

 You didn't loose your bootloader, you cannot loose it. Probably your options bytes were accidentally messed up. See this link:

Thansk!  I loaded the option byte and this what I got.

0x1FFFF800 00FF5AA5 00FF00FF 00FF00FF 00FF00FF Does that look right to you?  Do you have a valid option byte for a STM310E-EVAL (STM32F103) that you can send me? I also loaded the flash registers.  They are all at their reset value.  The ''OPTERR'' bit on ''FLASH_OBR'' had not been set either. Thansk, Ben

I think Ben is referrering to boot strap code in flash, not the ROM based loader. Pretty much the entire flash rom is game for being bricked. I have a STM3210E-EVAL on the bench, will pull the FLASH image off.(ZIP'd binary attached)

Thanks clive1!  That did the trick!  My STM3210E-EVAL is working again.  Couple things... I had to power cycle the device.  Reset had mirror images of what I was expecting.  Also, would you happen to know where in RAM the boot-strap-code is typically located?  How can I make that I don't over write it in the future.

Thanks again, Ben
