TMS320C5515 spi EEPROM boot

Other Parts Discussed in Thread: TMS320C5515

Dear all;
I have a question about eeprom boot of TMS320C5515. Bootloader application note says that to boot from an spi eeprom,you should connect the CS of the eeprom to CS0 of DSP.I am a bit confused here because TMS320C5515 has 2 SPI_CS0 connections which can be selected using different EBSR PPMODE :one of them locates at P4 (LCD_CS0_E0/SPI_CS0) other locates at P11 (LCD_D[9]/I2S2_FS/GP[19]/ SPI_CS0). Which one of them is selected by DSP during booting process? Is both of them selected consecutively one another?

CS0. I think you know by now since I answered a similiar question by you. Please close this one if done.

Dear Steve;
I mentioned that CS0 must be used by spi EEPROM for boot.But which pin should be connected ?P11 or P4? or it does not differ?

The device tests for SPI boot on SPI_CS0 in Parallel Port Mode on External bus Selection Register set to mode 5 and then mode 6. For mode 5, SPI_CS0 is on P11, for mode 6, SPI_CS0 is on P4.
