## 2 HW problems [last week](https://hackmd.io/yRC0m0U-QHG_czFufaG24w#5-Problems-about-generate-hw_targer-for-build-sw)

Problem:

* `write_hw_platform` -> Output to *Vitis*
* Failed
* `write_hwdef` -> Output to *SDK* but deprecated since vivado 2019.2
* OK (But Warning about *SDK* has been deprecated)

[Solution:](https://forums.xilinx.com/t5/Design-Entry/ERROR-Common-17-69-Command-failed-write-hw-platform-is-only/m-p/1197468/emcs_t/S2h8ZW1haWx8YW5zd2VyX2FjY2VwdGVkX2FzX3NvbHV0aW9ufEtLNjhPR0xFSEtSWjNDfDExOTc0Njh8QUNDRVBURURfU09MVVRJT05TfGhL#M25728)

* `write_hw_platform` only work in the
1. tcl-project-mode
2. tcl-non-project-mode must read-in *.dcp* file first
* command `read_checkpoint` is differernt from `open_checkpoint` , see above xilinx forum link
* `open_checkpoint` = `read_checkpoint` + *do stuff for initialization*
* so only `read_checkpoint` still don't use `write_hw_platform`

Note:
Actually,
I read a lot of docs which never mentioned this thing.

## 3 Build SW
