4 Replies and 1698 Views How do you display a picture?  1698  4 Started by  Deleted User Hello Everybody, How do you display a picture (In code, no LOLO) This is what I had tried: I partially took this from one of the demos in the kit. The demo was clearing the video buffer, so instead of *pbf=0 I replaced it with a color 0x01E0 (green), but it looks weird, it does not paint all the vertical lines why also would this display my picture if I do this: pfb = &40;UNS_32*&41;SRAM_PHYS_BASE while &40;&40;UNS_32&41;pfb < &40;image DISPLAY_WIDTH*DISPLAY_HEIGHT&41;*2&41;&...

0 Replies and 1717 Views malloc error when try to mount CF card  1717  0 Started by  Anonymous The LH75401 standard memory configuration does not have enough memory to handle the File Allocation Table (FAT) for many CF cards. It will work if the FAT is small enough – it can be reduced by ensuring the card being used is a small card (16MB) and the file structure on the card is minimal. You may have to create a smaller partition on the card as well to minimize the file system size. Using WIN2000 to create a FAT file structure has not been shown to work. The file structure is too large....

1 Replies and 1789 Views putting code in onchip SRAM  1789  1 Started by  Deleted User I would like to direct that several files from my program go to onchip SRAM for faster execution. The program compiles and runs fine if I put it all together in off-chip SRAM using the default linker script. But when I put this in the linker script&058; . = 0x80000400; .text2 : { oscillator.* (.text) } I get errors like: Dwarf Error - invalid or unhandled FORM value 14. This post suggests I need a new binutils: http://gcc.gnu.org/ml/gcc/2002-02/msg00965.html I also get an error: 'reloc...

1 Replies and 1587 Views Problem bringing up Bootloader  1587  1 Started by  Deleted User Hi, I just bought a Zoom Starter development kit with the card engine LH75401. I installed the Tera Term software and powered up the board. I did not see what you show in the Fig 4.2 - LogicLoader Menu. Instead this is what I saw. 'LLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLL ' I have connected to Com2 and I know com2 works very well with my other application. While running Tera Term - it's the only that is accesing Com2.
