Hello guys,

first of all - thanks for this great forum. Found many hints here already.
Currently I'm working with a STR9 Comstick from Hitex, Yagarto and OpenOCD.
I arrived at the point where I have to flash my hex-file but... the following problem occures - maybe you can figure out what I'm doing wrong.

Have you tried :
flash erase 0 0 2
(ie. just erase the first 3 banks rather than all 4)

If this works then you have the same problem as I do with an LPC2119 and that someone else has in this message : viewtopic.php?t=9191

There is definitely something fishy about the erase command parameters; I am currently trying to figure it out as I am certain that in my case the flash bank statement in my config file is correct.

[edit] For LPC processors at least, the top 8k of flash is the boot sector; maybe erasing it would destroy the boot loader? [/edit]

Sorry I can't be of further help.

The error means the bank is protected, mainly because of the config you are using - normally this would be used if you have remapped Bank0/1.

To get started i would use the default setup - Boot bank is Bank0.

str9x flash_config 0 4 2 0 0x80000

and
flash bank str9x 0x00000000 0x00080000 0 0 0
flash bank str9x 0x00080000 0x00008000 0 0 0
in your config

everything else looks ok.

Hello,

it works!
So the problem was the order I specified the flash banks, right?
How should they be specified - or how do I know which flash bank has to be defined first?
And most interesting question - is this kind of reflecting the content of the STR9 boot bank configuration registers?

Thanks!!

regards,
Daniel

[ntfreak]

The str9 has a complex flash controller on board, so if have remapped the boot bank you will need a different config.

You have to make sure the flash bans and the flash_config config lines match.

For most people using the default above is ok.

I'm currently coding a bootloader and want to use the flash controller to remap the boot bank (32k) to be the startup bank.

So what I did was...

... configured the flash banks in the order I thought it should be.

Code: Select all

# first flash bank (boot bank)
flash bank str9x 0x00000000 0x8000 0 0 0
# second flash bank (app bank)
flash bank str9x 0x00080000 0x00080000 0 0 0

... then I started ocd and set the flash controller

Code: Select all

#str9x flash_config <bank> <bbsize> <nbsize> <bbstart> <nbstart>
str9x flash_config        0          0              4            0x0         0x80000

#bbsize register = 0 : means 32kBytes (written in the STR9 flash programming manual)
#nbsize register = 4 : means 512kBytes (written in the STR9 flash programming manual)

Where did I make the failure? I don't get it

*EDIT* I used exactly the configuraiton and flash_config you provided and was able to erase the bank 1 sectors (boot bank). But I got the same error 0xa2 when I tried to erase the bank 0 sectors (appl. bank).

*EDIT2* Whenever I use the str9x flash_config command to reassign the memory mapping of the banks... Do I have to disconnect and reconnect the power supply so the new register values are used? Or is it enough to do a reset after the flash_config command?

Help appreciated

[ntfreak]

First use str9xpec to configure boot bank:
flash bank str9xpec 0x00000000 0x00080000 0 0 0

str9xpec enable_turbo 0
str9xpec options_read 0
str9xpec options_cmap 0 bank1
str9xpec options_write 0

then cycle board power.

Then configure banks as follows:

flash bank str9x 0x00000000 0x00008000 0 0 0
flash bank str9x 0x00080000 0x00080000 0 0 0

str9x flash_config 0 0 6 0 0x80000
flash protect 0 0 3 off
flash erase 0 0 3
flash write_binary 0 image.bin 0

much easier to use autoerase
flash auto_erase on
flash protect 0 0 3 off
flash write_image image.s19

and to verify write
verify_image image.s19

EDIT: Which revision do you use?

[ntfreak]

rev 278 from svn

Cheers

[mydev]

Do you know where I can get a more recent version? Maybe daily/nightly build for windows?

[ntfreak]

Michael Fischer should be updating the version on his website very soon:
http://www.yagarto.de

The other way is to download the source and build.

Cheers
Spen

[mydev]

I downloaded the newest version from the yagarto homepage - and everything is fine now!
Thanks a lot for being so patient ntfreak

Damn, I was lucky too fast...
Sometimes when erasing flash it's hanging and openocd is reporting this problem:

By default the comstick has a 25MHz osc onboard.
your jtag speed to is high
jtag_speed 1
should fix the problem, try even slower if you still get problems.

Hm,

I think I killed my ComStick somehow. It's impossible to flash it, even by using Hitop.
