Re: [Openocd-development] SRST TRST have to be buffered?

Thanks! That's good to know. I didn't realize that the STM32 can reset itself, too. That would be problematic. I suppose if I never use low power mode, I can omit both resets. Matthew On 7/22/2011 12:12 PM, Andreas Fritiofson wrote: On Fri, Jul 8, 2011 at 1:19 AM, Matthew Lai cyberf

[Openocd-development] STM32F2 flash size detected wrong

2011-07-26 Thread Matthew Lai
Hello! I just started working with a custom PCB STM32F2, and while I got most things to work (including flash and verify), OpenOCD seems to detect the size of flash on my chip wrong. OpenOCD (poll) reports 1024KB, when the chip is a STM32F205RET6, with 512KB flash. The flash size I

I see. Thanks for the clarifications! I understand the purposes of the buffers much better now. Matthew On 7/8/2011 12:50 AM, Laurent Gauch wrote: Hello! I'm trying to embed a FT2232D based programmer into my board with a STM32 (Cortex-M3 MCU). I want the programmer to be compatible with

Ah! I see. I guess it's fine as long as OpenOCD either tristates or drive high the reset lines when it's not doing anything. Is that the case? Thanks! Matthew On 7/8/2011 9:51 AM, Phil Fong wrote: ** I'm

Hello! I'm trying to embed a FT2232D based programmer into my board with a STM32 (Cortex-M3 MCU). I want the programmer to be compatible with jtagkey, so I looked at schematics of compaible designs. I noticed that while the JTAG signals (TCK, TDI, TDO, TMS) are only buffered when
