Test item: mPCIe -> SATA converter ASM1061 hdd: Seagate Laptop SSHD 1000GB 8GB NAND flash

  1. mPCIe1 without resistor

    Note that CLKREQ has been already turned off for mPCIe1 when these test were proceeded.

    • Cold boot: it takes 60-75 sec after power-on until boot menu appears. There is no HDD entry in boot menu.

    mPCIe1 behaves the same for both mPCIe -> SATA converterts

  3. mPCIe2 without resistor

    • HDD not detected neither in bootmenu nor in OS

  4. mPCIe2 with resistor

    • HDD not detected in bootmenu

    • After cold boot there is boot menu entry, but cannot boot into OS from mSATA or USB. When loading into OS it reboots after:

    • then infinite coreboot loops:

  5. After setting CLK3 (GFXCLK) to be always on (just like it was done for mPCIe1 and CLK3 before):

    • mPCIe2 without resistor behaves the same as mPCIe2 with resistor before this change (coreboot loop)

    • mPCIe2 with resistor behaves the same after change

    so: turning CLK to be always on (to ignore CLK_IRQ) causes mPCIe to treat card without resistor as the one with resistor

  6. So there are two cases:

    • long coldboot (AHCI timeout in SeaBIOS) and no bootmenu entry for mPCIe1 (but after reboot it's OK)

    • coreboot loop for mPCIe2

  7. Connect HDD to SATA (J7)

    • regular boot, bootmenu entry appears after cold or warmboot
    • it is handled by IDE (ata.c) not AHCI (ahci.c) - when connected through mPCIe converter it was handled by AHCI

Long boot log:
