Dear All,

I want to make u-boot resolution 848x480. How can I calculate
resolution parameter like that videomode.c?
        /* x y pixclk le ri up lo hs vs s vmode */
  {640, 480, 39721, 40, 24, 32, 11, 96, 2, 0, FB_VMODE_NONINTERLACED},
  {800, 600, 27778, 64, 24, 22, 1, 72, 2, 0, FB_VMODE_NONINTERLACED},
  {1024, 768, 15384, 168, 8, 29, 3, 144, 4, 0, FB_VMODE_NONINTERLACED},
  {960, 720, 13100, 160, 40, 32, 8, 80, 4, 0, FB_VMODE_NONINTERLACED},
  {1152, 864, 12004, 200, 64, 32, 16, 80, 4, 0,
FB_VMODE_NONINTERLACED},
  {1280, 1024, 9090, 200, 48, 26, 1, 184, 3, 0,
FB_VMODE_NONINTERLACED},

Thank you for your help in advance.

Selim.

Hello,

I have bought an inexpensive JTAG XDS510-UB2.0 clone from

www.00ic.com (TI’s original part is far to expensive for me).

Now I want to “debug” mainly the DSP of the BB but up to now

I have not much luck!

I have created a new board based on the template of my cheap JTAG

emulator and have duplicated all settings from the original TI OMAP3530

XDS510 board.

After removing the GEL file from the ICEPICK_C component I was able to

connect to it :slight_smile:

But no luck for the C6400PLUS (GEL also removed)

Error connecting to the target:

Error 0x80000240/-1146

Fatal Error during: Initialization, OCS,

Invalid data was scanned by the emulation controller.

Verify the board setup to make sure the scan chain is properly defined.

If the setup is correct, then RESET EMULATOR. This will disconnect each

target from the emulator. The targets should then be power cycled

or hard reset followed by an emureset and reconnect to each target.

I/O Port = 240

Board Name: Beagleboard

Cpu Name: C6400PLUS_0

or the CS_DAP_PC component (GEL also removed)

Error connecting to the target:

Error 0x80000240/-5005

Fatal Error during: Initialization, OCS,

Unknown Error

I/O Port = 240

Board Name: Beagleboard

Cpu Name: CS_DAP_PC_0

Has anybody out there such an cheap emulator successfully running with an BB?

Could the errors be due to running Windows XP and CCS within a virtual machine from a linux host?

Could this be due to the BB hardware revision C4 (720 MHz)?

Any help would be great!

Thanks in advance!

Regards

Martin
