Driver for the on-chip serial devices (sci) will be available soon. -(2) The present 'hw_init.c' file is incomplete and does not set all - registers required for serial I/O. The effect is that the sci devices - are 'muted' and do not successfully transmit characters to the respective - I/O lines on the SH7045F. If these ports have been properly initialized, - they are not disabled by the current code. A two-part initialization will - be available soon. +(2) The present 'hw_init.c' file provides 'early_hw_init'(void) which + is normally called from 'start.S' to provide such minimal HW setup + as is conveniently written in 'C' and can make use of global + symbols for 7045F processor elements. It also provides + 'void bsp_hw_init (void)' normally called from 'bspstart.c', shortly + before RTEMS itself is started. + + These are both minimal functions intended to support the RTEMS test + suites. |
