| |
− | Firsts test applied to 1 hand labeled board:
| |
− | * Visual mount inspection --> OK
| |
− | * Check main sources: 5V; 1V8 (WIFI clean); VDDQ; VTT; 1V2; 2V; 1V8 (V_1P8); 3V3 (V_3P3); VCC_MAIN --> OK no SS
| |
− | * Overall consumption: 5V@0.21A ---> OK, less than Qseven and Sondrio but not dangerous
| |
− | * Removed Standalone Marvell debug flex connector ---> OK. Broken some NC pads from footprint
| |
− | * Add wires to get acces to JTAGB connector ---> OK
| |
− | * Test 25 MHz crystal --> add R950. OK
| |
− | * Test power pin decoupling mounted resistors--> OK
| |
− | * Add PU (4K7) to PRI_TRST into board. The others PU has been added to converter --> OK
| |
− | * Mounted 26 MHz oscillator --> OK
| |
− | * Umount all POWER bad resistors --> OK
| |
− | * Add 330 nF to 3V3 enable LDO to delay 3_3P3 power source (RC: 10K/330nF) ---> OK
| |
− | * Add 0R to R75 and R80 ---> OK
| |
− | * Mount R931 to get access directly to eMMC ---> OK
