Hello,
I've got an i210 connected to an SoC and for production I'd like to write the external eeprom via PCIe:
- I map the config space and access the IO area via the config space registers 0x98/0x9C
- The semaphore and sync between FW/SW seems to work
- I write the config (0x80 16bit words) to the SRAM and can read it back, checksum is 0xbaba
Triggering the flash write via FLUPD fails: FLUPD is already set to one by the first write to the SRAM?
After the first SRAM write via EEWR, EEC reads: 0x482a00, is this correct?
When will FLUPD be reset? By whom?
Also I'd like some more documentation on two registers:
Chapter 8.4.2 describes EELOADCTL:
This register provides software EEPROM-mode load status.
All bits are RW to FW, RO to host - excepted to bit 12.
Then it gives a short table for bit0 all ohters are reseved, a second, completely different table describes bits 0:32.
In chapter 8.4.5 EELOADCTL is described a second time with a single sentence.
EELOADERR is in chapter 8.4.4 but there's no description of the bits (table missing?)
Can you please provide me the missing/correct tables for these registers?
Best regards,
Lo
