![]() ![]() Up to 2 Mbytes of embedded Flash memory, with Read-While-Write capability on certain devices.Up to 16 Kbytes +16 Kbytes of I-cache and D-cache.AXI and multi-AHB bus matrixes for interconnecting core, peripherals and memories.The STM32F7 series unleashes the Cortex-M7 core: Smart architecture with new peripheral set Taking advantage of ST’s ART Accelerator™ as well as an L1 cache, STM32F7 microcontrollers deliver the maximum theoretical performance of the Cortex-M7 core, regardless if code is executed from embedded Flash or external memory: 1082 CoreMark /462 DMIPS at 216 MHz f CPU. And as ST-Link, it’s fully compatible with STM utilities.STM32F7 series of very high-performance MCUs with Arm ® Cortex ®-M7 core Another disadvantage has been mentioned here.īut all in all, it’s a useful tool. One disadvantage is that ST-Link is for STM32 ♜’s only, whereas BMP can work with ARM ♜’s from a variety of vendors. When copying a “.bin” file to it, it will upload that file to the attached target board. Like all Nucleo boards and all MBED-enabled boards in fact, this board shows up as a memory disk when plugged into USB on Windows, Mac OSX, or Linux. in addition, it’s a CMSIS debugging interface, allowing “st-util” to use it with gdbĪnd last but definitely not least: it’s a memory stick.it’s also a serial-port pass-through, using the “st-term” tool.it’s an ST-Link programmer, so the “st-flash” tool by texane can be used.But that is actually quite a nice tool as is: What we have here is merely an ST-Link V2.1 for external use. ![]() We’ve not created a Black Magic Probe – that would require re-flashing the ♜ on the ST-Link. The alternative it to simply cut off the ST-Link board and be done with it.įor information on converting the somewhat older Discovery boards to a BMP, see this page on – it considerably more work, though definitely possible.īack to this Nucleo now. To restore the previous use, you can simply add a solder drop and make sure it covers both pads of the jumper. Note that these are the famous “0Ω” resistors: i.e. Or just apply more heat and unsolder them properly. The quick-and-dirty way is to break those resistors with a small cutter, and then remove the debris with a soldering iron. ![]() But if you also want to use the ST-Link for the RX, TX, SWO, or NRST pins – you need to cut those connections. If you only use SWCLK and SWDIO, then you’re done. Solder jumpers SB12, SB13, SB14, and SB15 are used to connect the ST-Link to the rest of the board. But if you leave the ST-Link attached to the rest of the board you must make some changes to make it work for external use – here is the underside of the ST-Link: Warning – Without external hook-up, you can still use the ST-Link as programmer for the attached Nucleo. Why this layout? Because pins 2.7 match the programming header on a HY-TinySTM103T.
