master branch is broken

[chegewara]

Here is what i get after building and flashing master branch:

[MAIXPY]Pll0:freq:832000000
[MAIXPY]Pll1:freq:398666666
[MAIXPY]Pll2:freq:45066666
[MAIXPY]cpu:freq:416000000
[MAIXPY]kpu:freq:398666666
[MAIXPY]Flash:0xc8:0x17
open second core...
gc heap=0x801700e0-0x801f00e0
[MaixPy] init end
Traceback (most recent call last):

If i build and flash from my repository, which is about 2 week behind, it works. EDIT: this is the reason why its dirty:
