Not yet figured out how to read cy7c68013 eeprom. --- End quote --- The cypress chip has no internal eeprom, the FW is stored in a eeprom chip 24LC64 (IC U807) on the other side of the board, and it is loaded to the MCU during power up. Which version of the HT6xx4 do you have? If you can damp yours EEPROM content and post it here it would be nice. There is no hardware difference among the models, the BW is limited in software. |

Just wonder if anybody can upload the eeprom from 6254bd model |

I have the eeprom from a 6074bc and I would like to compare it to the 6254bd model, maybe the BW configuration is in there as the hardware are the same. |

Spent some time reversing pcb, so here are my recent findings regarding fpga pinout: --- Code: ---// ADC HMCAD1511 CSn B2 SDATA A2 SCLK B3 RESETn A3 PD C3 DP1A B5 DN1A A5 DP1B B6 DN1B A6 DP2A C7 DN2A A7 DP2B B8 DN2B A8 LCLKP C9 LCLKN A9 FCLKP B10 FCLKN A10 DP3A C11 DN3A A11 DP3B B12 DN3B A12 DP4A C13 DN4A A13 DP4B B14 DN4B A14 // DAC902 CLK E16 PD J14 DB11 F15 DB10 F16 DB9 G14 DB8 G16 DB7 H15 DB6 H16 DB5 J16 DB4 K15 DB3 K16 DB2 L16 DB1 M15 DB0 M16 // leds nLED_green B1 nLED_red C1 // out square 1k OUT1K E3 // main fpga clock 24M coming from quartz oscillator near cypress.

Hey many thanks for the firmware, i am little noob in these i2c field can any of you guys help me trough the process of backup and write the firmware in my unit, many thanks, if you have some link to tutorial video or make a quick one will be great. (mine is bricked itself no red light blink anymore) thanks a lot. [EDIT] Just found these hey great work! https://sigrok.org/wiki/Hantek_6022BE https://sigrok.org/wiki/Hantek_6254BD (seems same of 6xxxBC mine 6104bc is same) https://sigrok.org/wiki/Hantek_6052BE |
