HALCoGen bug in driver for I2C2 on RM57L843ZWT

Other Parts Discussed in Thread: HALCOGEN

It looks like there is a bug in the I2C2 code generated by HalCoGen for Hercules RM57L843ZWT.

The I2C2 interrupt handler, if enabled, handles the TX ready interrupt by writing data to the I2C1 DXR register. I found the source of the issue in the following file:

C:\ti\Hercules\HALCoGen\v04.05.02\drivers\TMS570LC435ZWT\I2C570v000\i2c.c

line 984 in the I2C2 interrupt handler is:

i2cREG1->DXR = (uint32)*g_i2cTransfer_t[1U].data;

This is obviously incorrect.

Details:

  • HALCoGen 04.05.02
  • Target: RM57L843ZWT_FREERTOS
  • I2C2 is enabled
  • I2C2 interrupt is enabled
