questions regarding evkmimxrt1024_lpi2c_interrupt_b2b_transfer_master

[ping1]

Dear all

Would like to try this example with a RT1024 board as master and another RT1064 board as slave, connected as following SCL: J18-12 to Rt1064 J23 -6, SDA: J18-10 to RT1064 J23-5, and GND: J19-14 - J23-7.  

 I downloaded both firmware down to the boards , however, it doesn't run as expected , in RT1024 master transfer function line below

 reVal = LPI2C_MasterTransferNonBlocking(EXAMPLE_I2C_MASTER, &g_m_handle, &masterXfer);

The reVal = 900, not kStatus_Success. So it doesn't transfer at all.

I am using both SDKv24.12 and IDE24.12 as well.

Please help!

Hello @ping1,

I connect the RT1024-EVK and the RT1064-EVK with you pin configurations and both examples work as expected:

In order to support you better, can you provide me the next information?

-Could you share your current connections?

-Does the issue always occur, or does it appear spontaneously?

Hi, Habib

thanks for your try, checked wiring again, and found a mistake, it is working now.

Sorry for my mistake!
