3 Replies and 1489 Views library functions in arm-elf-gcc  1489  3 Started by  Deleted User Hi, I have managed to successfully compile the serial port echo sample application for the SDK75401 and load an execute it without a problem. I have been using cygwin and the compiler from the CD which came with the SDK. When I try to extend the sample program with calls to library functions such as sprintf() or strlen() and other such functions, the compiler reports it cannot find the header and library files. Am I missing something in the make file or linker script A quick search of the...

1 Replies and 1348 Views JTAG startup  1348  1 Started by  Dpac Does anybody know the start routine for the LH75401 We’ve recently built our own hardware and I’m trying to get the processor running. I’ve got a Wriggler JTAG a BDI2000 and a greenhills probe on lone. Amazingly the wriggler JTAG works and I can view and edit registers however I can’t seem to boot the system with any of the other JTAGs. I know that I need to set the cspr, RCPC and WDT need to be set but what else needs to happen. Are there any other registers Greenhills had an example start...

1 Replies and 1436 Views What are the best development tools to use?  1436  1 Started by  Dpac Hi I'm just starting out in arm development and wondering what people recommend are the best development tools to use for the LH75401. The main part of our project is to use the TFT controller to produce a nice GUI. I was hoping to achieve this without an OS and by just running the PEG libraries. I've had a few recommendations to buy the Multi ICE JTAG. Are there any other tools that I need Is it worth spending large amounts of money on an expensive IDE such as the Real View Development tools...

3 Replies and 1420 Views Macraigor's Wiggler and Raven debugger don't support LH75401  1420  3 Started by  Anonymous The problem is believed to be related to the Wiggler not being able to handle the adaptive clocking on the LH75401 ARM7TDMI core. The Raven has not proven to work consistently with the LH75401 either. Logic recommends the ARM Multi-Ice with the LH75401. It works with the LH7A400 and LH79520 as well.

1 Replies and 1662 Views Flash Programming  1662  1 Started by  tsetsinas Hi, we want to program the flash memory without using BoLo/LoLo. We have erased the flash and we are trying to burn our image at address 0 with arm realview ice tools. We use a program algorithm from intel and we get Low programming voltage detected from flash status register. We also checked this signal (FL_VPEN) with oscilloscope and is always low. Device commands that don't check VPEN (eg. read device id) work fine. Can you suggest something Is it necessary to use BoLo Thanks

2 Replies and 1355 Views Interfacing with a STN LCD  1355  2 Started by  Deleted User We will be using the STK to interface to a STN display. If I read the documentation correctly, open_video allows me to do this using supported display option 3, LM057QCTT03. First, is this assumption correct Second, do you (or I) have a document that describes the interconnections (If I read the documentation correctly, all the signal names in the LCD connector are called out for interface to a TFT display). I'm going to take a shot at picking the right signals, but I'm sure to run into t...

3 Replies and 1374 Views Where is the LH75401-11 sample zoom app?  1374  3 Started by  Deleted User I've looked all over but I don' know where the sample app code is. The docs imply that it's on the CD in \Software Development Tools\sample_zoom_app but that folder contains one file: README.txt, which talks about copying the files from this folder to the PC - BUT there aren't any other files there. The instructions for the Macromedia startup (in the user manual) say to go to Software Development Tools, then select install on the fourth item (4.

Changes in Hardware and Software must be made to account for this. Hardware: If you add additional SRAM to the card engine please refer to the LH75401-10 card engine schematics (pg. 4) for memory location and jumper setting changes.
