Isp Pinout ~repack~ | T580

CS is never asserted, or the chip is not powered. Solution: Verify that the T580 has standby power (measure 3.3V on pin 8 of the BIOS chip). Ensure CS is correctly connected to the programmer’s CS pin.

But Kael saw a puzzle.

, you must solder fine wires to specific test points on the motherboard. The following pins are typically required for a stable connection DAT0 (Data 0): The primary data line for communication. CMD (Command): Used to send commands to the eMMC. CLK (Clock): t580 isp pinout

Remove the bottom cover and disconnect the internal battery and the CMOS (coin cell) battery. CS is never asserted, or the chip is not powered
