----------------------- Release 2023.2-b4283 ---------------------------

2023-06-09 LEON5 updates:

- Implemented data\_store\_error trap with configurable handling of special cases (such as interrupt between store and error)
- Implemented internal cache error trap for critical errors (duplicated tags detected)
- Add cache trap register to record delivered and pending and traps from cache controller.
- Support write combining mode based on explicit hint instructions instead of always waiting for following store
- Add full barrier and write combining hint using existing STBAR opcode (consistent with SPARC V9 MEMBAR)

2023-05-25 AHBCTRL simulation trace updates:

- Print correct slice for narrow accesses on little endian buses.
- Trace SPLIT and RETRY responses in addition to OKAY and ERROR.
- Optionally prefix each trace line with bus index and/or a custom debug tag provided as a generic. Intended for multi-bus systems.

2023-05-25 AHBJTAG and TAP techmap:

- TAP techmap now uses BSCANE2\_TAP for all Xilinx technologies where the built-in TAP is accessed using a BSCANE2 primitive.
- Added new generic taptecharg in AHBJTAG which is passed to the TAP techmap. Currently used only by BSCANE2\_TAP to select an alternate user scan chain.
- JTAGTST jread procedure now supports custom ainst/dinst/isize.
- AHBJTAG documentation updated.

The new grip.pdf ([https://www.gaisler.com/products/grlib/grip.pdf](https://www.gaisler.com/products/grlib/grip.pdf)) shows that the L2C-L has added diagnostic access support.

May I ask if the corresponding GRLIB will be released in the near future?
