That also allows you to try to flash via USART1. ehobby on "STM32 Discovery" http://forums.leaflabs.com/topic.php?id=630#post-105230 Wed, 12 Feb 2014 21:08:58 +0000 ehobby 105230@http://forums.leaflabs.com/ Yes, all power and GND are connected accordingly and the reset pin is set to momentary low. I also put BOOT0 to low. Is this correct? It looks to me somehow the device can not be found.

With gbulmer's help, I was able to do it successfully. Now I am trying to download the codes to a real uC chip(the same one as in the VL discovery board). I use the same four wires connecting them to CN2 on the discovery board, removing the two CN3 jumpers, wiring the uC power pin64 to 3.3V and pin63 to GND. JTCK is connected to pin49 and JTMS to pin46. Using the Keil with ST-link set to SW mode, it says 'No Cortex-M SW Device Found' in the SW device settings, and 'No target found' when I try to download the codes. Any idea what I might have done wrong? Your help is greatly appreciated!

It is 52MB, compressed, so it is not a Maple program, and must instead be run. That has the same properties as a virus. The second lnk is to an article which reads like a large add for commercial product. So it doesn't make much sense. So your post looks very like SPAM, or a virus spreader. Would you please improve the links, so they are understandable and relevant to the post, or remove them? Otherwise I feel I need to do something to reduce the risk of spreading a virus, or publishing spam. I recommend people do not download a zip-like file unless you understand exactly what the unpacking process involves. I recommend people do not run any download unless you understand exactly what it is, trust the source, and know that the file is uncorrupted.

It sounds like, maybe, the two ST-Link SWD headers are connected together, and not the ST-LINK of one board (CN2) to the STM32F100RBT6B MCU on the other. Edit: That document shows a schematic diagram for the ST-Link part of the board on page 20/22. That shows CN3, the header with the two jumpers, connects to the STM32F100RBT6B SWCLK on pin 2, and SWDIO on pin 4. Also, pin 1 of CN3 connects to 3.3V, and pin 3 to ground. That is the same layout as the SWD socket (CN2) pin description on page 10, Table 2. So remove the jumpers from CN3 on both boards, then connect the SWD socket (CN2) from the board used for ST-LINK to the CN3 socket of the 'target' development board. Edit 2: Based on the schematic on page 22, Figure 14, the SWD sockets pin 1 is not connected to power, so the target needs to be powered too. This enables all 4 pins of the SWD (CN2) header to be connected to the 4 pins of CN2, which makes sense (easy to connect). ehobby on "STM32 Discovery" http://forums.leaflabs.com/topic.php?id=630#post-30206 Sat, 14 Sep 2013 12:40:25 +0000 ehobby 30206@http://forums.leaflabs.com/ gbulmer, Thank you for the quick response. Yes, STM32VLDISCOVERY is the board I was referring to. I have two of this boards. So for the test, I connected the 1st board with the USB cable, removed its CN3 jumpers, then made a 4-wire connector to connect the SWDs on both boards (I intended to use the 2nd board as an external chip here). However the ST-line program kept complaining that no target can be found (I tried this with CN3 jumpers both on and off for the 2nd jumper). Do you know what I did wrong?

You don't need to buy an ST-LINK/V2. If you do decide to buy an ST-Link, get the newer ST-LINK/V2 as it uses a updated protocol which is reputedly friendlier to some operating systems. The older ST-LINK did present a slight problem on a Mac. ehobby on "STM32 Discovery" http://forums.leaflabs.com/topic.php?id=630#post-30204 Sat, 14 Sep 2013 11:58:37 +0000 ehobby 30204@http://forums.leaflabs.com/ Hello there. I just discovered the STM32F100 value line discovery board about a month ago. So far I had fun running a few blinking programs on it. I am now trying to build an application on a real chip. It seems to me that I can download the program to the external chip using the on-board ST-link utility with the CN3 jumper removed and the SWD pins connected to the SWD pins of the external device. Is this correct or do I have to purchase the ST-link debugger to do the download?

I tried using the latest code there from git and it compiles but doesn't run on the discovery board, even using the USER_ADDR_ROM, USER_ADDR_RAM changes. Also, slightly unrelated but I can do pretty much everything with anton's fork, but I'm trying to merge the code I saw on the forums for hardware flow control and that uses more recent code from the official branch. Would anyone be interested in lending me a hand with flow control?
