I am using T1023 with RCW set to serdes (0x99) , uboot boot up shows
Corenet Platform Cache: 256 KiB enabled
Using SERDES1 Protocol: 153 (0x99)
SEC0: RNG instantiated
NAND: 0 MiB
MMC: FSL_SDHC: 0
SF: Detected S25FL512S_256K with page size 256 Bytes, erase size 256 KiB, total 64 MiB
EEPROM: Invalid ID (ff ff ff ff)
PCIe1: Root Complex, no link, regs @ 0xfe240000
PCIe1: Bus 00 - 00
PCIe3: Root Complex, no link, regs @ 0xfe260000
PCIe3: Bus 01 - 01
my questions are
1. why no link shows here? my ITSSM value is 0. (I got a PCIe device connected...)
2. I observe the same log "no link" on the T1023 reference board, is ITSSM supposed to be 0 even with no PCIe device?
3. Could you show me how the ITSSM process is triggered, is there an enable register of the PCIe controller?
