=== IGEP0040-RA03 version - Micron memory ===
 
 
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, but 1.27 mm header can be used
 
* Add wires to get acces to JTAGB connector ---> OK
 
* Test 25 MHz crystal --> add R950, because datasheet recomends. 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
