Hi, as far as I can see you don't have provided a CLKOUT connection from the LPC24xx to the FPGA. This would be very helpful for synchronous data transfer to/from FPGA. This clk signal should be feed to a pin of the fpga which can be routed to the internal PLL/DLL for a little time shift of the FPGA internal clock with respect to the clk signal the LPC will output at the pin. This would spee...

Hi Friends, I am doing a Jtag Programming for SPARTAN FPGA using ARM. I just gone over the algoritham of XILINX JTAG programming. The algoritham is made into a program and just it is toggling of pins. The hex file for the FPGA is get through the UART and sending as a bit stream to the FPGA JTAG pins.But my program is not working in the FPGA.

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, ...

Hi I need to interface an FPGA to the external bus of the LPC2294 so that I can directly read and write to the BlockRam internal to the FPGA (Arranged as a dual-port RAM).

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...

I've been asked to find the costs of swapping one of our LPC2294 prototypes onto FPGA. If the move gets the OK, this is going to be a complete SoC design (with a soft core). I've done various ARM7 (and PIC) designs but this will be my first FPGA project. In the archives for this group there is some discussion about some free tools from pdqlogic http://www.pdqlogic.com/index.html. Thi...

Hi, Last few days I have spent on learning about CPLD and FPGA. It appears that prices of these devices are coming down. I have also found that 8 bit (pico blaze) and 32 bit (micro blaze) micro controller are also being implemented on FPGA.

Hi all, I am working on a new project using the LPC3240 controller. To communicate with an external FPGA I use SSP0 with DMA. The behavior observed with the oscilloscope looks fine as the data sent and received are correct. The settings are : data width = 16 bits. The upper 8 bits are FPGA commands, and the lower 8 bits are the FPGA answers. data burst = no What I observed with the o...

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.

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...
