So actually the reason it does not boot is that U-Boot does not see the eMMC device at all. I'm really wondering if it was installed at all!
- => bdinfo
- arch_number = 0x00000000
- boot_params = 0x00000000
- DRAM bank = 0x00000000
- -> start = 0x00200000
- -> size = 0x08200000
- DRAM bank = 0x00000001
- -> start = 0x09400000
- -> size = 0xE6C00000
- baudrate = 1500000 bps
- TLB addr = 0xEFFF0000
- relocaddr = 0xEDD5B000
- reloc off = 0xED35B000
- irq_sp = 0xEB9F9020
- sp start = 0xEB9F9020
- FB base = 0x00000000
- Early malloc usage: 32f8 / 80000
- fdt_blob = 00000000eb9f9038
- => mmc list
- dwmmc@fe2b0000: 1
- dwmmc@fe2c0000: 2
- sdhci@fe310000: 0
- => mmc dev 1
- MMC error: The cmd index is 1, ret is -110
- Card did not respond to voltage select!
- mmc_init: -95, time 10
- => mmc dev 2
- MMC error: The cmd index is 1, ret is -110
- Card did not respond to voltage select!
- mmc_init: -95, time 51
- => mmc rescan
- MMC error: The cmd index is 0, ret is -110
- mmc_init: -110, time 5
Copy the code
=> this is totally bogus!
The only way I managed to flash the device was by leaving a virgin SD card in the slot. Otherwise it refuses to flash, which makes sense of course, if the eMMC is not accessible from the boot loader!
So now I have no idea what to do. I think ,I'll ask for a refund because at this level it's a real abuse, they're selling a device that cannot work at all and are blatantly lying to their customers without making any effort to provide working images nor considering their questions. |
