3230 Hanya bisa Hidup dgn Battery

3230 Hidup dg Batt n kondisi Contact Retailer
Ditest dg PSU -> gx short
Dg UFS, hny bisa di Check -> 1st n 2nd boot n Flash terdetect semua
Flash complete -> tetap gx bisa boot ke any mode (Local, Test or Normal)

Praduga awal BSI pada jalur flash pin bermasalah, ternyata semua dlm kondisi OK ..
Dicheck hambatan Dioda pd pin2 flash tersebut n dibandingkan dg table normal,
Utk WD2 dg nilai:
1 = 1
2 = 0.610
3 = 0.550
4 = 0.700
5 = 0.745
6 = 0 (Ground)
7 = 0.880
8 = VBatt

3230 xg bermasalah:
1 = 1
2 = 0.480
3 = 0.588
4 = 0.705
5 = 0.750
6 = Ground
7 = 0.880
8 = VBatt

Hambatan pd jalur 2 berubah naik 0.200+
Dimana Pin 2 = jalur VPP, tegangan Boot Local Mode 3.2V terhambat menjadi lbh kecil ke UPP
Karena dijalur tsb gx ad resistan luar, di simpulkan kerusakan pd UPP 90%

Dicoba ambil tegangan dr Pin8 (VBatt dr Box 4.2V) dg di kasih resistan diantara'y sekitar 100K utk menghambat arus guna mencegah jebol di proses software

Hasil'y 3230 bisa langsung Local Mode n di Info:
