I have an application where I want to use the LPC2148 to receive and store on SD card the configuration file for an FPGA and subsequently use the file to configure the FPGA at startup. No problem here as there is sample code at OpenCores for doing this with an 8051 clone. However, my typical FPGA application can use some serial ports. Something on the order of 4 seems about right. So, ...


EBI synchronization on LPC2378

Hi, I am working on a new design that involves an LPC2378 and an FPGA, in which we plan to map specific hardware. The FPGA will be accessed via the EBI. The problem is that the FPGA will require a clock and I don't seem to find the EBI clock on the bus. Is there any way to retrieve it? An alternative would be to use the LPC2468 in SDRAM mode but this would also increase the complexity of...

Hey everybody, We're about to design a development platform with the LPC 2378 and an FPGA (Lattice XP). Our problem is that the 2378 seems to support only an asynchronous bus, and we suppose that we will have problems with the clock. Has something similar been done before, and are there any application notes? Regards, fireprint


LPC2138 another try on freertos

Hi all, I am going to try again to port the freertos for this combination: - LPC2138 with just one uart (uart1) readily available (there is a fpga between uart1 and the serial port configured to forward data to the pc). Uart 0 pins are available and can be connected to the fpga as well but not both at the same time. - 24MHz fixed clock (slave from a FX2 chip), I would like to reach 48MH...


UART0 - does not work while UART1 does

Hi, I need someone to be mercy and send me a compiled gcc example of a program to send test chars on uart0 and uar1 for a LPC2138@24MHz. I cannot think anything wrong with what I do and that basically works for uart1. Uart0 is connected thru an FPGA, Uart1 is directly connected to a serial port. The fpga is programmed to just forward the signals between the LPC2138 and a serial port. O...

Hi, We've written a Windows 2000/XP based IDE (called ArmEd) which interfaces with the GNUARM toolchain & Insight debugger. It also uses OpenOCD to interface to the target JTAG port. You can create and configure projects very easily, then build, download & debug them. The IDE was developed for use with a LPC2214/FPGA development board but can be used with other LPC2xxx targets. An ...

Hi, we just got first prototypes of a new board with LPC2468 (beside an Actel Flash FPGA, SDRAM and MicroSD slot). Without DBGEN, the LPC responds to an UrJTAG "detect" with a proper response that I expected for Boundary Scan mode: IR length: 3 Chain length: 1 Device Id: 01000000000111110000000000101011 (0x00000000401F002B) Manufacturer: Philips Semi.

Ok, so it seems I'm not the only one concerned with BGA prototyping or 'hobbiest' use of such devices. What kind of expense have people experienced for board manufacturing? I have used subcontractors to load boards with *LOTS* of BGA devices, and if I recall correctly, there was a $3k NRE charge to setup the reflow machines. We had a bad FPGA on one board, and that same company was able t


Fast ADCs and LPC

I have a project that requires two 12-bit ADCs with parallel output and a sample rate of ~20-30 Msps. The micro will be processing the data into a bit stream, formatting that into a data packet and sending it out via a canned wifi solution. I could use an FPGA instead of a micro but it would add a lot of cost and time to the project. I could just try it with an LPC1769, 120MHz, FIQ, for exa...

I am working with an engineer who is designing a system around the LPC2388. The engineer has created a board that places much of the system I/O in the EMC memory space through a couple of FPGA's containing all the glue logic. The engineer has not been able to get the interface to work. A review of the Errata for the LPC2388 notes that there is a bug in the EMC that could explain this. However...

Hello, Is there an LCD to VGA ready-made circuits out there? (basically FPGA+RAM) I was able to generate VGA 640x480 timing using an LPC2478. This greatly slowed down the system, due to the high load on SDRAM. Now, to go to higher resolutions, it is not much of an option on LPC2478. I have seen a VGA frame generator chip before that have built in frame buffer and then you can use LPC248 to ...

I use LPC2378 with the mini bus. Because the software was written when only rev '-' was available I had to access the external FPGA (8 bit wide) with the GPIO pins. And this worked OK. Now I have the revision A and tried to use the EMI. I tried several configurations but had problems to access the 8 bit periphery. BLS0 is used as write strobe. When I write a single byte I get 4 write strobes...
