A Note on Using
the High-performance Embedded Workshop V.4.00.00
--On Specifying Address Parameters in HDI Commands--
|
Please take note of the following problem in using the High-performance
Embedded Workshop V.4.00.00, an integrated development environment:
- On specifying address parameters in HDI* commands
* Hitachi Debugging Interface
- Product and Version Concerned
The High-performance Embedded Workshop V.4.00.00
To check for the version number of your High-performance Embedded
Workshop, open the Help menu and select the About High-performance
Embedded Workshop command.
- Description
If the address parameters of the HDI commands hdi assemble, hdi memread,
and hdi memwrite are set to 0x80000000 or greater in a CPU with 32-bit
memory space, the problems explained below arise.
| (1) |
In the hdi assemble command
Command syntax: hdi assemble <address> <instruction>
Problem: If the address parameter is set to 0x80000000 or greater,
the result of assembling the instruction parameter cannot
be prpvided.
Example: hdi assemble 0x80000000 NOP
|
| (2) |
In the hdi memread command
Command syntax: hdi memread <space> <address> <count> <size>
Problem: If the address parameter is set to 0x80000000 or greater,
data cannot be read from memory.
Example: hdi memread 0 0x80000000 1 1
|
| (3) | In the hdi memwrite command
Command syntax: hdi memwrite <space> <address> <size> <data>
Problem: If the address parameter is set to 0x80000000 or greater,
data cannot be written into memory.
Example: hdi memwrite 0 0x80000000 1 1 |
- Workaround
Don't set the address parameters of the HDI commands hdi assemble,
hdi memread, and hdi memwrite to 0x80000000 or greater in a CPU with 32-bit memory space.
- Schedule of Fixing the Problem
We plan to fix this problem in our next release of the product.
