Re: Tempest C1 flash without mass erase

I just wasn't using the write_bank command correctly I think:

Code: Select all

reset halt
flash erase_sector stellaris 4 255
flash write_bank stellaris file.bin 0x1000
reset run
With a linker setup with 0x1000 offset seems to work.

Tempest C1 flash without mass erase

I posted my question in a relevant thread I found but it was very old. Tempest C1 revision devices have a flash patch and lock the flash from mass erase. I normally call write_image erase blah for flashing LM3S devices. Calling this without the erase still seems to "auto erase" write bank fails with...

Tempest C1

Madis or anyone else can you tell me how to program the LM3S9xxx chip without using mass erase?

write_image seems to automatically call mass erase even without the "erase" command. I am using the most reason OpenOCD development release. Tired issuing sector erases but it seemed to just hang on those.

Re: Segfault while flashing Stellaris CortexM3 with openocd

So for the openOCD script this board has one built in. I use a recent dev release of OpenOCD and don't have any issues under Ubuntu with this board.

Linux RAM needs

For people who have ported Linux to a micro, what is sort of the minimum amount of RAM the board needs to have for it really to be useful/easy to port? (I am talking full regular 2.4 or 2.6 kernel).

Re: Unfair! I want to sell PCB's too!

But in the US that isn't true, and if Sparkfun sends you a check they have to tell the IRS something about it I would think. They don't want to have to abide by every countries laws and know them all, so everyone who isn't in the US is out of luck because it would cost a lot to obey all the laws... ...

Taxes

This probably has to do with making money and reporting taxes. I would guess.

While I know lead free solder is harder to work with I think it is a brave new world and I probably will have to get used to it RoHS may be coming even the US shores. So I am thinking of starting some SMDing and am wondering if you guy have any recommendations on Pb free paste, the Easy 256 SF sugge...

Re: Luminary BD-ICDI-B Ubuntu issue

It appears to be a bug introduced in the FTDI driver in the kernel reverting to 2.6.32-24 resolves the issue. (Issue is in 2.6.32-25)

Luminary BD-ICDI-B Ubuntu issue

I am using Ubuntu 10.04, this is less an openOCD issue than a JTAG/Linux issue. Summary: my configuration doesn't seem to let me access the UART properly in the ICDI board if you have it working please read and let me know. Without rules in /etc/udev/rules.d The ICDI doesn't work without sudo... The...

Re: OpenOCD on linux, no /proc/bus/usb

The ARM-USB-TINY should not need anything custom to work at all (FTDI driver is in the kernel if you build openOCD you will have to include FTDI library support), I used it with the openOCD 0.3.1 binary that was in the Ubuntu 10.04 package sources... I haven't tried it since moving to 0.5.something ...

Re: LMS9B92-B1 dev board with OpenOCD

Hi Spen,

Thanks for the reply. I know what git so you are telling me to build the current branch to fix this basically is how I read that. Sorry I am not a very linuxy person as yet...

EDIT:

Done and working better now.

LMS9B92-B1 dev board with OpenOCD

I believe this may have been discussed somewhat before here, but I didn't fully follow: http://www.mail-archive.com/openocd-development@lists.berlios.de/msg13001.html I am hoping someone wiser in OpenOCD will know. I have a LMS9B92 dev board. Chip is rev B1. I am using the provided "ek-lm3s9b9x.cfg"...

BGA/PCB manufacture

First of all does anyone have experience to know if BGA with just hot air reflow works well, (or maybe skillet or oven). I would like some processors that only really are available in BGA. Also does anyone know of good places that would actually do the whole PCB/assembly of parts in relatively low n...
