Posted on February 04, 2015 at 12:58I am using ULINK-PRO to debug a STM32F4. I have connected the target as per the Cortex Debug+ETM 20 pin. I have connected TRACE_D1 to nTRST as I believe these pins are multiplexed within the ULINK PRO. i.e. nTR...
Posted on November 26, 2012 at 14:05I am using a STM32F4 FSMC to address external 16-bit SRAM on a custom board. Everything is OK. I want to connect an external FPGA and I'm not so clear about the actual addressing. Please correct me if I'm being s...

Posted on February 08, 2012 at 20:30I am new to arm and designing a new prototype board with a STM32F417 and 2 NAND Flash chips. In the data sheet it says the HCLK can go to 168MHz BUT it also says that the FSMC maximum clock is 60MHz at 3.3V. Does...
Posted on February 08, 2012 at 21:37 Just found the answer to my own question, the data sheet, page 61 table 11 just says FSMC maximum clock frequency which I took to be the HCLK in, but it actually means the maximum external access frequency!
