Error while accessing iMote2 flash using OpenOCD

Development Boards MicroMod

Hi,

I am trying to access the flash in my iMote2.

I am using a Olimex JTAG ARM-Tiny-USB interface with openocd in Ubuntu.

When I start the openocd, it gives the following error,

Open On-Chip Debugger 1.0 (2009-11-20-12:42) svn:516

$URL: http://svn.berlios.de/svnroot/repos/ope … /openocd.c $

Info: jtag.c:1329 jtag_examine_chain(): JTAG device found: 0x79265013 (Manufacturer: 0x009, Part: 0x9265, Version: 0x7)

Warning: jtag.c:1157 jtag_check_value(): value captured during scan didn’t pass the requested check: captured: 0x00 check_value: 0x02 check_mask: 0x07

Warning: jtag.c:1117 jtag_read_buffer(): in_handler reported a failed check

Error: xscale.c:804 xscale_write_dcsr(): JTAG error while writing DCSR

But I am able to telnet to localhost 4444 and I am able to get the flash info etc (flash erase_check, flash protect_check, flash info & all works fine!!!).

But when I tried to erase a sector/write into any erased sector, it gave the following error,

flash erase_sector 0 243 243

status register: 0xfe

Block Lock-Bit Detected, Operation Abort

Program suspended

Low Programming Voltage Detected, Operation Aborted

Program Error / Error in Setting Lock-Bit

Error in Block Erasure or Clear Lock-Bits

Block Erase Suspended

couldn’t erase block 243 of flash bank at base 0x0

failed erasing sectors 243 to 243 (-902)

Can Anybody tell me what could go wrong here ?

I am attaching the config file which I used for openocd. Please have a look.

Also, is there any version of JMMFlash which works with USB interface ?

Please advise …

Thanks in advance

Jithin Jose

C’mon - you’re using r516 while SVN was succeeded by GIT around r3000… Your version is prehistoric… Compile / Get yourself a more recent version first.

4/3!!

Thanks for replying, Freddie.

I tried with the latest version. But I am getting some new errors this time!

For flash commands it gives the error, “Target not halted”

and for halt command, it gives the error, “Target not examined yet”.

While starting the openocd, I got a lot of errors,

The config files i use are the ones which come with the installation, arm-usb-ocd.cfg (http://www.cse.ohio-state.edu/~jose/pub … sb-ocd.cfg)(I had to modify the description and ID in this), crossbow_tech_imote2.cfghttp://www.cse.ohio-state.edu/~jose/pub … imote2.cfg, pxa270.cfg http://www.cse.ohio-state.edu/~jose/public/pxa270.cfg.

I am attaching the debug log file also … http://www.cse.ohio-state.edu/~jose/public/logfile.log

  1. Try a stable release - like 0.3.1 (0.3.0 is broken - don’t touch it). This way you’ll get rid of those “command_register” errors - that’s some new stuff they’re working on right now

  2. The connection to imote doesn’t seem to work well - the returned value (0xff) is completely wrong, and I cannot help you much here. Maybe try adding a jtag_khz option somewhere and adjust the speed? This should be about 1/8 of the core speed after reset and because you don’t have that option anywhere, FT2232 works with a 6MHz default clock (the core should run with at least 50MHz after reset). Maybe decreasing this to a lower value (1000 - for 1MHz or even less) will help?

4/3!!
