1. Symptom: This test uses reference power supply HYNIX 8G eMMC will Fail, Fail to power analysis HYNIX 8G eMMC. (OCR register [31] bit is 0). <br>2. wonder: Fail reason to doubt: LDO5 advance LDO10 power-up, time: 240us; MMC controller MCU end of the IO leakage to the MMC controller 8G eMMC end, leading to the HYNIX 8G eMMC electric Fail. <br>3. Verification: If the power LDO10 LDO5 before, then the PASS Test HYNIX 8G eMMC; <br>if MMC controller MCU and the terminal ends of the MMC controller 8G eMMC are LDO5 power, then HYNIX 8G eMMC test PASS. <br>4. Note: LDO5 after power on, before LDO10 power, the MCU will not HYNIX 8G eMMC transmits a command and data read and write. <br><br>The following issues need to confirm the work of Song <br>1. MCU end of the MMC controller power than HYNIX 8G eMMC end of MMC controller earlier in the power, then this will not affect the power of HYNIX 8G eMMC? <br>2. HYNIX 8G eMMC of MMC controller before power on the requirements of the external leakage current?
