1355SHOW Demonstration Program
Issue Date: 98/10/29
ERROR: Could not initialize device.
These messages generally mean that the given hardware/software setup violates the timing limita-
tions described in the 1355 Hardware Functional Specification, document number X23A-A-001-xx.
ERROR: Unknown command line argument.
An invalid command line argument was entered. Refer to the help screen or documentation for valid
command line arguments.
ERROR: Too many devices registered.
There are too many display devices attached to the HAL. The HAL currently supports only one
device.
ERROR: Could not register SED1355 device.
A 1355 device was not found at the configured addresses. Check the configuration address using the
1355CFG configuration program.
ERROR: Did not find a 1355 device.
The HAL was unable to read the revision code register on the SED1355. Ensure that the SED1355
hardware is installed and that the hardware platform has been set up correctly.
ERROR: Continual screen read will not work with the /a switch.
The continual screen read function reads one screen indefinitely, so it is not possible to automatically
cycle through the video modes.
WARNING: b= option used with /noinit, so bit-per-pixel and display
memory will NOT be changed.
The b= option requests that registers be changed for a given bit-per-pixel mode, while the /noinit
option requests the opposite. To resolve this contradiction 1355SHOW will not change either the
registers or the display memory. Consequently “1355SHOW b=?? /noinit” is only useful for contin-
ually reading the display memory.
UNSUPPORTED MODE: Cannot show ?? bpp in portrait mode.
Only 8, 15, 16 bit-per-pixel modes are supported in portrait mode.
ERROR: Could not change to ?? bit-per-pixel.
The HAL library detected that the requested bit-per-pixel mode will violate the hardware specifica-
tions for clocks. To reprogram the clocks, run 1355CFG and select the desired bit-per-pixel mode.
