I am not able to get the ST Flash loader to recognize the STM32 on the MP32. I get the following error: 'No response from taget, the Boot loader can not be started. Please, verify the boot mode configuration and the flash protection status.' Settings-Config: A) ST Flash Loader: 115200, 8, even, (echo disabled).

B) I am using an ftdi usb-232 converter with a 232 shifter smd at the end (): A picture of my configuration is at the bottom. Regarding B, this seriel configuration is working when I connect to either of the usarts on the StmDiscovery board. In fact on the discovery board, with respect to usart#1, I am connecting to pins Pa9 & Pa10 (same as MP32). I am noticing that when I press next on ST flash Loader I can see the Tx and Rx blip momentarily, and then the Rx led on the 232-ttl converter stays on slightly dim (until I press the reset button on the MP32). When I power up the board with the 'jumper' removed, JP11-5 is High and JP11-6 is low. I am not 100% sure, but I believe JP11-6 corresponds to the Boot_0 pin on the STM32.

I tried several different buad rates in Flash Loader, but didnt have any luck. Also, I tried all the above on my deskop (which has serial ports). I used the same level shifter at the end of the cable. In all the above I also tried switching the Rx and Tx going to the MP32 (in case I had them backworks)s. I even tried pressing the reset after powering the board up, before trying the use the Flash Loader.

The only thing I didn't think of until now (editing post) is that on the Discovery Board I powered the 232=ttl convertor at 3.3. When connected to the MP32 it is being powered at 5. What level is the usart at? Is there anything I overlooked? Thanks, JimT Tags. Hello Jim, I am using a USB FTDI Cable.

I have setup the same parameters as you for serial setting. I am using TTL Tension, i.e 5.5V as this is supported but 3.3V is ok also. You should remove the jumper and reboot the proc to activate the serial bootload process. Initially I have the same trouble.

My mistake was an inverted connection of the Tx/Rx connector! Then, I have a problem in the following menus of ST Flash Demo when trying to upload a binary File. In the ' Download to Device' selection, you should activate the 'Global Erase' Option to be able to load correctly a binary file. This option is not setup by default! Hope this help!

Univega serial number years. I just picked up a Gran Premio for $150 in pretty decent condition that I'm configuring. That being said it is still a bike and if you need one and craigslist, ebay, or wherever seems pretty stale this could be a solid ride. Look for Japanese made, skip over Taiwanese 80s steel bikes.

I guess the converter I bought isn't as smart as a max232. After getting some sleep I looked at the differences between the config above and the Discovery board, and realized the diff was that on the discovery board I was using 3v3 (NOT 5v). Well, I hope I didn't exercise anyone needlessly, especially Roberto. For anyone having this issue, trying to use the same 232-TTL converter; here is a pic of what works: • • Reply by on March 25, 2011 at 6:16pm. I actually experience the same problem, i.e., the Flash Loader Demonstrator won't always recognize the MP32. Sometimes I have to try several times until it finally recognizes it. I am also using the 5V output of the MP32 as the power supply for the RS232/TTL converter.
