Tool/software: TI-RTOS
Dear All,
I designed custom board using TMS320C6657. And I succeed to boot with test code image (GPIO LED test code) from SPI NOR Flash with DDR initialization.
I connected SPI NOR Flash to SPISCS0 (SPI CS0).
When I succeed to boot, I set "csel = 2" in nysh.spi.map, and set boot mode pin BOOTMODE [8:7] to "10".
I succeed to boot and I have a correct SPI CS0 pin interface.
I followed SPIboot_with_DDR_UserGuide from below link.
But I change SPI NOR chip select signal from SPISCS0 (SPI CS0) to SPISCS1 (SPI CS1).
Also I modifies nysh.spi.map like below and re-run spiboot.bat:
section {
...
csel = 1 /* for SPI CS1 */
...
}
And I set boot mode pin BOOTMODE [8:7] to "01". But there is no SPI CS1 after power on or reset.
Isn't it possible to boot from SPI CS1?
Thank you and best regards.
