First, Did you set to boot pin to active high?
If you set to boot pin to active high, You possible connected to ISP serial access.
And I think, W7500P still have locking.
So, check to sequence to below list. (below list is W7500P make to unlock mode way)
- Access to ISP tool serial.
- Check to All Code Read Unlock/Data R/W Unlock of Step 3
- Check to All Code Write Unlock of Step 4
- Do not load binary file.
- ISP start click. (This is unlock setting to W7500P chip)
And exit to ISP program.
And then reexcute ISP program.
If you successfully unlock to W7500P, ISP tool show to same below picture.
If ISP tool show to same below picture, You possible W7500P memory R/W.
