hi.

Now I'm writing I2C master program referring to the following.

FM_PDL_2.0.1/example/mfs/i2c/i2c_polling/i2c_master_polling/main.c

To read some data from slave to master, the sample program is using I2c_Read().

And this function is calling Mfs_I2c_ConfigAck() to send ACK or NACK to slave.

But the description of Mfs_I2c_ConfigAck() says "Configure ACK signal sent to master", "This function is only meaningful when I2C is in slave mode". (mfs.c L.3527~)

Can I use Mfs_I2c_ConfigAck() in master program?

Why I ask this, my I2C master program (on FM0+ S6E1C) has stop in Mfs_I2c_GetStatus() loop (main.c L.272~) after reading first byte. So I doubt that NACK has not been transmitted properly.

The 1 byte looks like correct, but can't read any more.

thanks.

Hi,

I want create a loader for 91F469G mcu, this loader I want write to I/D_RAM memory area (for example from 0x00030000 address) using internal bootloader commands (write, call, ..).

I am using Softune V6. What linker settings should be for this project?

Is the MB88121C/CY88121C FlexRay controller available? Is this an active and recommended product? Which is the correct P/N? Where the related documentation can be found on the Cypress website?

I am using softune IDE for sw compilation and editing.When I tried to download code into MB96F348 controller it I showing error that " Boot ROM " file not found.

Dear sir

I am newbie in bootloader. I use mcu MB95F698K. I am trying to use Interrupt Vector Table in both bootloader and application but seem like it can't. Do you have any solution to use it in both bootloader and application ?

Thank sir
