Hello!

I'm trying to get Olimex ARM-USB-TINYH working with a custom STM32 based board. The main problem is very slow flash programming speed (fastest i've got is 0,323838 KB/s). Previously we used Olimex ARM-JTAG-EW and with it got flash programming speeds around 11-12 KB/s.

Any ideas?

I'm using precompiled Windows OpenOCD that come in CD with Olimex ARM-USB-TINYH.
Flash programming is done with the following commands:

openocd -d2 -f "scripts/interface/olimex-arm-usb-tiny-h.cfg" -f "scripts/target/stm32.cfg" -c init -c halt -c targets -c "flash write_image erase image.elf" -c "verify_image image.elf" -c "reset run" -c shutdown

I have following configuration files:

olimex-arm-usb-tiny-h.cfg:

Code: Select all

interface ft2232
ft2232_device_desc "Olimex OpenOCD JTAG ARM-USB-TINY-H"
ft2232_layout olimex-jtag
ft2232_vid_pid 0x15ba 0x002a

stm32.cfg (little-bit modified from original):

I've tried various jtag_khz values, but if I set it higher than 500, OpenOCD outputs "Error: SWJ-DP OVERRUN - check clock or reduce jtag speed" messages. "reset_config" parameter is taken from old configuraton file used with ARM-JTAG-EW.

Also, at the begining OpenOCD outputs following messages:

Code: Select all

Error: AHBAP Cached values: dp_select 0x0, ap_csw 0xa2000012, ap_tar 0xffffffff
Error: SWJ-DP STICKY ERROR
Error: Read MEM_AP_CSW 0x23000052, MEM_AP_TAR 0x4
Error: AHBAP Cached values: dp_select 0x0, ap_csw 0xa2000012, ap_tar 0xffffffff
Error: SWJ-DP STICKY ERROR
Error: Read MEM_AP_CSW 0x23000052, MEM_AP_TAR 0x4

Don't know what this means actually, but OpenOCD can write image successfully.

What drivers do you use? ftd2xx or libusb-win32?

OpenOCD 0.3.0 is broken and un-usable - use some other release.

when ı used openocd-ftd2xx.exe
and used argements : -f "olimex-arm-usb-tiny-h.cfg" -f "lpc2378.cfg"
then getting this info and error..

any ideas?

Idea: Don't use ancient OpenOCD with modern config files.

I downloaded openocd 0.4.0 ver. then used argements : -f "olimex-arm-usb-tiny-h.cfg" -f "lpc2378.cfg"
again then getting this info and error..

"Error: EmbeddedICE v7 handling might be broken" what does this mean dude? Do you think about where is my fault?
thx for supply.

Ignore that - everything should work normally.

I have received this 'error' as well. If it is not something to be concerned about, why is it flagged as an error?

Is there a way to make it go away? I have a zero tolerance rule on warnings and errors!
