Xrpc call list

XRPC_ID_GETSERIAL (0)

Returns the chip serial number.

	param0	param1	param2	param3	param4
input	0	0	0	0	0
output	serial number [0..31](LSB)	[32..63]	[64..91]	[92..127](MSB)	0

XRPC_ID_GETRANDOM (2)

Returns a random number generated by the chip hardware, this xrpc takes about ~10ms

	param0	param1	param2	param3	param4
input	0	0	0	0	0
output	Random Number	0	0	0	0

XRPC_ID_GETBONDINGCOMMENT (3)

Returns the chip bonding option string in param0 and param1, "developA" for development chips (ES4/ES5/ES6/ES7) or "productA" for production chips (revA/revB/revC/..)

	param0	param1	param2	param3	param4
input	0	0	0	0	0
output	Bonding comment [0..31] (LSB)	Bonding comment [32..63] (MSB)	0	0	0

XRPC_ID_SHA1XOS (4)

Returns the SHA1 hash of the xos currently in serial flash.

For 'M' versions of xos (development versions), the last 3 hex digits of the hash are normally equal to the release version (since xosM7d), this is not true for 'P' (production) versions of xos.

	param0	param1	param2	param3	param4
input	0	0	0	0	0
output	xos SHA1 hash [0..31] (LSB)	[32..63]	[64..91]	[92..127]	[128..159](MSB)

XRPC_ID_XLOAD (5)

Load a secure binary in xload format (payload)

	param0	param1	param2	param3	param4
input	Size	Depends on xload cert type	0	0	0
output	Depends on xload cert type	0	0	0	0

• Param0 is the size of the xload payload, before encryption and formatting, not the size of the xload packet !
• For zboot/cpu type xloads, param1 is the load address.
• For xtasks and ucode type xloads, and from xos version >= D0, param1 is the dram controller to load the xtask too.
• Otherwise param1 is reserved (should be 0).

XRPC_ID_XUNLOAD (17)

Unload an xtask image previously loaded (payload is the corresponding xunload file)

	param0	param1	param2	param3	param4
input	Size of xunload payload	image number to unload	0	0	0
output	0	0	0	0	0
