I've got a network setup similar to this https://community.cisco.com/t5/switching/accessing-other-switches-from-core-switch/td-p/4869021, so the problem.
3650 switch - as a core and 2960 as an access switch.
The scheme is simple:
(router) -trunk- (Gi1/0/5 | core sw | Gi1/0/23) -trunk- (Gi1/0/21 | access sw)
172.20.190.1 - 172.20.190.11 - 172.20.190.11
management VLAN is 190, native VLAN 190 everywhere
I can ping core switch from router and vice versa, but I cannot ping access switch even from the core switch.
I tried to turn on ip routing, point to core switch as a gw, tried ACLs - no luck at all.
Here's my running configs
Any help will be appreciated!

Notr after you add vlan 190 don't forget do no shut for vlan 190 SVI

I simply didn't make Vlan190 active at the access switch. Silly me:)
Thanks a lot for pointing this out!

Hello
Edited{
disable ip routing on access switch and remove acl
Also you "core" switch isnt really a core switch its a host switch as it isnt running any routing, so you just have a single vlan transit through access<> core

Thanks for your reply, but ip routing wasn't an issue.
However, it must be disabled, I agree.
Ip routing was just an act of desperation same as the attempt of using ACLs
