The final solution: Full x1 pcie 2.0, 5Gps speed, power savings features

END OF PROJECT This story is about some researches and discoveries of Thunderbolt technology is ending. So that is results: 1. The connection of Apple Thunderbolt to Ethernet Dongle to Apple Wifi card from iMac: 2. Theory of how dongle caddy should look like: 3. How the rough soldering look...

I WAS READY TO CLOSE THE PROJECT AS I HAVE ALREADY DAMAGED 4x THUNDERBOLT DONGLES, TRYING TO ANALYZE DATA AND OTHER STUFF, WAS GATHERING THE REPORT ABOUT LAST FINDINGS AND DECIDED TO GATHER ALL DATA AT ONE PACK, AND... IT WAS AMAZING, WHAT I HAVE FOUND THERE! I am not a professional engineer...

TPS22924x 2A is N-Chanel On-Resistance Load Switch used to open 3.3v aux when Cortex-m0 have GPIO signal to wake system

Short DROM

Ethernet EEPROM Win capture - Aligned Ethernet EEPROM Mac capture - Aligned

DROM MODDING: offset 0x4C0 = CRC-8 checksum of UUID, next 8 bytes Calculate here <= offset 0x4C9 = CRC-32C starting from next byte (0x01), with length through one byte (0x6E) !!!!! (Keep in mind, that Generated CheckSum Should be converted from big endian to little endian ) Calculate here <=...

Some I2C capture from Ethernet EEPROM UPD1: New dump from new dongle: ST_M95160R_Ethernet3_Firmware.bin SysInfo: UPD2: New test Rig:

Some OC PCIe code from Apple

That is how SPI rom is read when dongle is connected to MBP. Interesting here is that DSL2210 never reads this code:

BQA, BQ8 STEP-DOWN 3.3V to 1.05V is TPS62510

HP ZBook Thunderbolt 3 - Dock A few images of logic board of Thunderbolt 3 Dock by HP and some firmware dumps. Images are not perfectly made, but could be useful for some repair stuff or enthusiastic interest. ICS: ASM1042A - DESCRIPTION ASM1074 - FEATURES DSL6540 - N\A BCM57762 - PINOUT...

I wasn't here for a long time, and sharing the materials never post before, that was used for analyze of this wonderful dongle. I am not 100% sure that everything there is correct, as it was my first study project, so...

Hi! I am not sure that this gpu support CSM. But you can try ZBOOK15_G3+G4_WX4150_HP_PEGABUILD.rom vbios version. Because mine build NEBULA, actually, for iMacs or Hackintoshes and about 8-12Kb of Legacy vbios was deleted, because at my testing gear it was working good so far, and it saves a...
