[Openocd-development] [PATCH] FT2232H/FT4232H support
Hi, I found some odd things in ft2232.c when it is built with FT2232H/FT4232H support : 1. It can only be built with the FTD2XX driver. libftdi supports FT2232H/FT4232H since version 0.16 2. A speed value of 0 is used as a RTCK request indicator. This clashes with the valid clock division value 0 that provide the highest fixed clock frequency. 3. The ft2232_speed_div function return the maximum selectable frequency (30MHz) when RTCK is activated. It should return 0. 4. The ft2232_khz function return ERROR_OK when RTCK is requested even for devices lacking RTCK support. It should return ERROR_FAIL so the upper driver layers can detect this and try to fallback to a fixed frequency. 5. FT2232H/FT4232H have a backward compatibility function that divide the clock by 5 to get the same frequency range as FT2232D. There is no code that disable this functionality. I can not find anything about if this is enabled or disabled by default. I think it is safest to actively disable it. The following patches is attached: p0_ft2232.patch Fixes item 1-5 above p1_readme_configure.patch Add test of libftdi for FT2232H/FT4232H support (version => 0.16) p2_readme_ft2232_configure.patch Renames the enable-ftd2xx-highspeed configure option to enable-ft2232-highspeed because builds with libftdi are also supported. The BUILD_FTD2XX_HIGHSPEED macro is renamed to BUILD_FT2232_HIGHSPEED for the same reason. p3_ft2232.patch Minimizes the conditional compiling that is dependent on the BUILD_FT2232_HIGHSPEED macro. I have tested both a libftdi and a FTD2XX build on a FT2232D (only a full speed chip) equipped interface. I have no acces to a FT2232H/FT4232H interface, so none tests have been done for these devices. The enable-ft2232-highspeed configure option could be removed so highspeed inclusion is only dependent on the FT2232H/FT4232H support check of libftdi/FTD2XX. This should be done after the code have been tested on a FT2232H/FT4232H interface.

But the same operations, halt then resume, will not let the console stop response with FS2. i agree with your comment that there are a lot interrupts running. But some interrupts have to finish its job when the cpu is unlocked, like uart. appreciate your help, miloody ___ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development

Everything works fine. As expected. it's working now on an LPC1768. The patch also fixes the handling of return values, and therefore the part_id sub-command is now working. Thanks Audrius!

Re: [Openocd-development] linux console will not out when openocdresume
I don't think this is an openocd issue. The kernel has numerous interrupts running. Generally speaking you can't halt a piece of software that uses interrupts and expect it to resume normally.

Re: [Openocd-development] linux console will not out when openocd resume
HI: 2009/8/13 R.Doss : > What do you undersand for linux? > The kernel or also all around? > > You need a bootloader and a rootfilesystem in addition to the kernel. Thanks for your reply. Maybe I need to describe my environment more clearly. I use initramfs as my root file system and use openocd to upload the whole kernel image, include root file system, to dram. Then set the pc to the kernel entry point, then execute. It works fine and I can get the console out. But my problem is if I halt openocd at this time then resume, the console will not get back. Sometimes I need to wait at least 1 min to get the console back, and sometimes it is fail. Is there any setting I need to take care? appreciate your help, miloody ___ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
