NXPTM LPC2XXX and LPC17XX / LCP177x/178x/18xx/43xx support
« on: November 10, 2010, 11:21:18 AM »
Hi Mark,

I've posted elsewhere about IAR v6 support & Cortex-M4 support... ;)

We're also trying out the new LPC1788 (Cortex-M3 core 'upgreade' from LPC2478) and are looking at the LPC18xx & LPC43xx families for some newer developments too.

Do you currently have any plans to support any of these? If so, what are your thoughts for availability of these?

I'd be quite happy to be an early test candidate for these - I'm trying to get a date when I can get some development boards at the moment. I'll let you know when I have a due date on anything.

Cheers,

µTasker general / IAR EWARM v6.10
« on: November 10, 2010, 11:16:48 AM »
Hi Mark,

I know it's just been released(!) but when do you think you will be able to offer support for IAR v6 for ARM platforms?

We've not yet set a date for moving to it, but looking at some of the features it offers (including the availability of Cortex-M4 processors from NXP & Freescale now) we'd certainly like to be able to work towards a date to aim for.

So, I guess I should also ask when you think you'll have Cortex-M4 board support? Even a rough date would help (e.g Jan 2011)

I understand that this may be a specialist request - maybe other users can comment on it if they are also after this support?

Cheers,

Hi Mark,

Sounds promising - I won't really be in a position to get to that part of the project for about a week or more, so if it's easier to aim for sometime late next week that would be fine for me!

(I'm trying to prove as much of the operation as I can on the LPC2478 at the moment & will be seeing how much works without change on the LPC176x once the basic functionality is pretty much there...)

Cheers,

Hi Mark,

I'm pleased to report that it works fine on the Olimes 1766 board as well - LED 1 flashes, LED 2 constantly on.

Any idea when the USB support may be rolled out for this (LPC17xx) family?

Cheers,

Hi Mark,

Thanks - I've got the code to compile ok now, just trying to get it to load onto the Keil dev board (via the IAR debugger if possible, which we use for our own development stuff).

Think I've got it sorted - hooray : LED P2.3 is now flashing .... ;D

Now I can try and get my own development rolling on the Keil board - I'll revisit the Olimex board again later and let you know how that one goes.

Thanks for all the help!

Cheers,

Hi Mark,

No problem re there being no IAR v4 project - v5 is my preference anyway  ;D

Ok, got the project file & copied into the existing file/folder structure.

I've tried compiling it for both the Olimex (LPC1766) & Keil (LPC1768) boards by changing config.h (#ifdef _LPC17XX) but both are giving an error "Error[Ta058]:ARM mode is not available in this core"

The first case for this is in LPC17XX.x, at line168
extern __interrupt void _start(void);

The problems mostly seem to relate to the use of __interrupt

Have I missed a change I need to make in config.h (or elsewhere)? I can see this being defined around line 54 in LPC17XX.c and if I change it so that the __arm is omitted (as for the non-IAR compiler case) that gets rid of the error re ARM mode.

That then leaves me with 5 other errors:-

Warning[Pe111]: statement is unreachable C:\Downloads\uTasker\uTaskerV1.4B_LPC17XX\Hardware\LPC17XX\LPC17XX.c 300
Error[Pe513]: a value of type "void (__interwork __irq *)(void)" cannot be assigned to an entity of type "void (*)(void)" C:\uTaskerV1.4B_LPC17XX\Hardware\LPC17XX\LPC17XX.c 523

Error while running C/C++ Compiler

I'm presuming that there's a similar change required to remove the interwork mode (which I think is an ARM/Thumb mode, not available for Thumb2 as used by Cortex-M3 ?) but I've not found this one yet.

Hi Mark,

I can't find a project for IAR (v4 or v5) in the beta of LPC17xx that I downloaded...I can see the folders for GNU/Rowley/uVision etc.

Is there any support for IAR (preferably v5 but I do still have v4.42 installed as well)? I think you had a bit of a fight with the i76 file back in March...

Cheers,

Hi Mark,

I will do - didn't get chance to try it last night but will make sure I do over the weekend.

We are interested in the USB support - I'll be interested to try this when it's available - but I'm not sure if we need the DMA. I can try it with the interrupt mode only as a first step and then let you know if the DMA would be useful.

Is the LPC17xx support in the normal LPC2xxx archive? I've just checked the download (using the link from the v1.4 e-mail in January) but I can't see any LPC17xx support...

Cheers,

Hi Mark,

I've just managed to borrow a Keil MCB1760 dev board (again) to go with the IAR equivalent I've had for quite a while.

Do you still want to know if uTasker works on the Keil board?

If so, I'll try and give it a brief run tonight and let you know how it goes.

Cheers,

Hi,

Would another option be to use a USB to SD card adaptor to provide USB host data storage support but without the problems arising from the many different flavours of USB Mass storage devices?

Just thinking (/hoping!) that once the USB to SD adaptor was working it should then basically work with any SD card plugged into it...

I'm not sure if SDHC support would be the next hurdle to overcome - anyone got any experience here?

We can't easily fit a removable SD card (or miniSD or microSD) in our products but we do have the USB Host connection available.

Cheers,

µTasker general / Re: Visual Studio C++ Express 2010
« on: April 30, 2010, 10:10:31 AM »
Hi Mark / Aaron,

I've just managed to download the old 2008 version of Visual Studio C++ Express - go to the 2010 download page

http://www.microsoft.com/express/Downloads/#2010-Visual-CPP

There's a set of 3 links underneath the Downloads - Visual Studio 2010 Express, SQL Server 2008 R2 Express, Visual Studio 2008 Express

Clicking on the 2008 one takes you to

http://www.microsoft.com/express/Downloads/#%20

Where there's a link for the 2008 express edition.

HTH

NXPTM LPC2XXX and LPC17XX / Re: USB for LPCXXXX
« on: April 15, 2010, 10:17:13 AM »
Hi Mark,

That sounds like great news!

We're using both LPC24xx & LCP17xx devices already and would be very interested in the USB functionality being included (both Host and slave/device) - USB mass storage would be useful but I'd also be interested in the BlueTooth option in your other thread.

We currently have our own separate module to provide BlueTooth to serial conversion into our products but these are certainly more expensive than a cheap USB to BlueTooth dongle!

Any further information you'd be prepared to share would be of interest!

Cheers,

µTasker general / Re: porting utasker to MCF5282 or other non supported targets
« on: April 04, 2010, 08:31:07 PM »
Hi,

Could you also please indicate which development board for the 5282 you've got the port working on - or is it on custom hardware?

We have a Freescale 5282 EVB board as well as our own custom designs.

Also, as a more general point, is there a guide to porting to different processors and/or custom hardware designs? Sorry if I've missed something but I couldn't see anything under the documents section.

We're using a variety of processor types (Freescale, NXP, Atmel, ST for example) and are keen to use uTasker where appropriate.

Any advice/help will be most welcome!

Cheers,
    Jez

NXPTM LPC2XXX and LPC17XX / Re: Where is the SPI clock speed defined at ?
« on: March 04, 2010, 11:04:08 PM »
Hi Mark,

I'd be very interested in the outcome of this as we have both Atmel 32MBit & SST 64 MBit SPI Flash connected to one SPI/SSP port of the LPC2478 on our design.

We're using the same port for both devices but using different GPIO lines to act as the chip selects for the two devices.

Basically, we're using the Atmel as NVRAM (as the erase & write sector size is the same) and the SST will be used as an off-chip file-store.

No desperate rush for this at present - I'd just like to know if/when it works. We're probably a couple of months away from needing the functionality at least.

Cheers,
    Jez

« on: January 27, 2010, 10:35:23 PM »
Hi Mark,

If you manage to add IAR support to the others, I'll be more than happy to try it out on the IAR dev board (which I think is a rebadged Olimex)!

Cheers,
