EEPROM install

Open Cabinfourus opened this issue 4 years ago • 7 comments

I have been trying to install the external EEPROM for more than two months. I keep getting the error for data size mismatch. I have tried different versions of Marlin, along with different configs. SKR 1.4 Turbo with TMC 2209 sensorless homing and 3D Touch sensor. I have tried adding #define I2C_EEPROM to the pins file without any luck.

I have the same problem, unable to make eeprom working

The same for me, I have installed the external BTT EEPROM and tried many different configs in Marlin but I always keep the same error. I have a SKR 1.4 Turbo with TMC 2209, 3D Touch sensor and Smart Sensor. I have tried adding #define I2C_EEPROM and also MARLIN_EEPROM_SIZE to the pins file and config file without luck.

Same for me,anybody find a solution???tried with any tutorial but nothing worked.

I've also tried with two different boards but nothing, the same problem. there is any way to contact the technical assistance?

Same issue, though; I use endstops and a genuine bltouch w/ 2209's. I'm also using power_control w/ dedicated 5v supplied to the board separately.

Hello. I use the EEPROM expansion module together with the SKR V1.4 board. I don't have a module from BBT but a clone from Aliexpress. But the use is the same. In order for it to work, it is necessary to edit the pin layout file. If anyone is interested, I can attach the necessary adjustments to make the module work. The module is connected to the I2C connector The first time you start, you need to initialize the EEPROM

// EEPROM I2C #define I2C_EEPROM #ifdef E2END #undef E2END #endif #define E2END 0x7FFF // EEPROM end address 24C256 (32 kB = 8 kB) //# define E2END 0xFFFF // end address EEPROM 24C512 (64 kB = 8 kB)

The patch was merged today In the pin layout file (pins_BTT_SKR_V1_4.h) just delete the comment on line # define I2C_EEPROM

So the entry will look like this // EEPROM #if NO_EEPROM_SELECTED #define I2C_EEPROM // EEPROM on I2C-0 // # define SDCARD_EEPROM_EMULATION #endif #if ENABLED (I2C_EEPROM) #define MARLIN_EEPROM_SIZE 0x8000 // 32Kb #elif ENABLED (SDCARD_EEPROM_EMULATION) #define MARLIN_EEPROM_SIZE 0x800 // 2Kb #endif
