Availabilty of redesigned LPC213X and LPC229X chips

Availabilty of redesigned LPC213X and LPC229X chips

2006-03-02 by alipowsky

Since juli 2005 we ask our Philips FAE and business contacts in
germany for a date, when redesigned chips of the LPC2134/6 and the
LPC2292 will be available.
The bugs around the timer/match/pwm ISR issue and the bugs in the CAN
controller have now turned into blocking points concerning the release
of some of our projects.

Every time we asked, we have got later dates, but not exact
information was given til today.

As we now have to make the decision to switch to another ARM-7
manufacturer. 
Before we go this unpleasant and expensive way, we would like to ask,
 whether anybody around here, has some secure informations about the
redesign schedules for the above mentioned cpu's.

Thanks 
Andreas

The LPC213x bugs have been fixed in the LPC214x, which is software 
compatible, and pin compatible except for pin 10 and 11.

...Ummm.....also... 
Questions of when philips is going to mask rom the 2 silicons:
LPC2114-LPC2294 and LPC213x-LPC214x, and default JTAG to DISABLE.

Though after so many heated arguments on flash protection and
conclusion of the 2 silicons are hack-proof, fortifying the read
protection will enhance users'/public's confidence.   

=> At least, with JTAG default as off,  we will not have any more
such discussions here and I think everybody will be happy!! :)

Can philips please help to MaskRom + JtagOff the chips??  
Many Thanks and I will switch from LPC2103 back to LPC2124.
Regards

We are also facing funny timer isr behaviour. 

I have written TImer ISR to generate one_sec bit and toggle an LED.

In main I dump a message on LCD display, and increment a step_number.

when quantity of this step crosses 20 or so, timer stops working, LED 
stops toggling.

We are using keil and LPC2132.

I want to know what is exact problem you are fcing. Is it same as my 
problem?

Yes Philips, please plug the hole(s) that do(es) not exist :)

Polling for data reception

2006-03-04 by Manisha

hi all,

i am designing a USB driver code in LPC2148 board. whenever the USB port
receives any data, it generates an interrupt.

However, i want to design my code by polling method, i dont want any extra
running context i.e an extra ISR. but as i found in the manual the bit in
the endpoint interrupt status register only indicates the reception. is
there any other bit or other CSR(Control status register) where i can get
indication for data reception and use that bit for polling?

Thanks for going through the problem.

please help me if anyone has any idea.

Regards

Manisha

You can always use the VICRawIntr register to poll the status of any 
interrupt, even those that are not enabled.

Richard.

2006-03-04 by Manisha

Hi Richard,

thanks a lot for the reply.
i was going through this VICRawIntr register. but, somehow i got confused
about the bits. the 22nd bit is for USB, but, for which interrupt, is it
specific for data in endpointOUT or it can be any inetrrupt. i could not
find any specific about this. it will be helpful for me if you share
something more about this.

again thanks a lot.

regards
Manisha Kalita

You can have a look at my open-source USB stack for the LPC214x
(see http://sourceforge.net/projects/lpcusb )

This code currently also uses the interrupt bit polling method.
The USB interrupt is not connected to the VIC and only the USBDevIntSt
register is polled.
In case the DEV_STAT interrupt bit is set, the code issues a Get Device
Status command to get the device event (reset, connect, suspend).
In case the EP_SLOW interrupt bit is set, the code can find out
exactly which endpoint(s) caused the interrupt by reading USBEpIntSt.
Each logical endpoint consists of two physical endpoints (for IN and
OUT), and each physical endpoint has a bit in the USBEpIntSt register.

Regards,
Bertrik

I don't know anything about the USB controller, because I never used an 
LPC214x. All I know that you can poll if an interrupt routine would be 
called if you enabled the interrupt, by reading the VICRawIntr register.

Richard.

Thanks Richard

actually i wanted to avoid any Interrupt routine.
anyway, i think i can use other interrupt status register bits also without
enabling them.

Manisha.

[lpc2000] indication for complete data transmission to USB host

2006-03-04 by Manisha

Hi all,

Thanks for helping me in solving the issue regarding polling for reception
of data.

now, i am stuck in an other problem. i want an indication whenever my USB
data gets transmitted succesfully to the host. in Atmel they provide one
TXCOMP bit which is set whenever the USB host receives any data and
acknowledges for the same. however, in lpc i have only TxENDPKT bit which
indicates only transfer of data to the endpoint FIFO. i want indication for
complete transfer.

can anyone help me in this regard?

Thanks for going through the problem.

RE: [lpc2000] indication for complete data transmission to USB host

2006-03-04 by Manisha

i think the problem i stated lately can be solved by checking USB Endpoint
Interrupt Status register (0xE009 0030).

any suggestion from your side will be helpful for me.

regards
Manisha.
