Could not put ADIN1200 into cable diagnostics mode with useful results.
Disable link (LINK_EN) - works an no link will be established when plugging in a cable
mii read 0x01 0x0017 0x3048 mii write 0x01 0x0017 0x1048
Enable diagnostic clock (DIAG_CLK_EN)
mii read 0x01 0x0012 0x0402 mii write 0x01 0x0012 0x0406
Run diagnostic (CDIAG_RUN)
mii read 0x01 0xBA1B 0001 <-- already at 0001, never resetted to 0000 mii write 0x01 0xBA1B 0x0001 mii read 0x01 0xBA1B 0001 <-- still at 0001, no reset
Read diagnostics results (CDIAG_DTLD_RSLTS_0, CDIAG_DTLD_RSLTS_1) - no changes no matter what cable
mii read 0x01 0xBA1D 1855 mii read 0x01 0xBA1E 0000
Result:
Could not create a PoC for the reset via the loopback/short-circuit detection.
The linux adin kernel driver 5.11 in contrast to the manual, clears the bit for diagnostic clock enable (DIAG_CLK_EN). What is right here?
Please give me a little help on how to test the cable diagnostic feature with u-boot's mii. A kernel update to 5.11 is not possible at short notice.
