MCU_SRAM_SIZE_KB does not propagate from i_mic_top to i_mci_reg_top

[noagurman]

MCU_SRAM_SIZE_KB is missing in the following instantiation

mci_reg_top #(
.AXI_USER_WIDTH(AXI_USER_WIDTH),
.SET_MCU_MBOX0_AXI_USER_INTEG(SET_MCU_MBOX0_AXI_USER_INTEG),
.MCU_MBOX0_VALID_AXI_USER(MCU_MBOX0_VALID_AXI_USER),
.MCU_MBOX0_SIZE_KB(MCU_MBOX0_SIZE_KB),
.SET_MCU_MBOX1_AXI_USER_INTEG(SET_MCU_MBOX1_AXI_USER_INTEG),
.MCU_MBOX1_VALID_AXI_USER(MCU_MBOX1_VALID_AXI_USER),
.MCU_MBOX1_SIZE_KB(MCU_MBOX1_SIZE_KB)
)i_mci_reg_top (

Opened an issue to the open source as well

Thanks for finding this issue. We will fix this issue in future revisions or if there is a critical patch release since this is not a showstopper issue.

FW can work around this issue by hardcoding MCU_SRAM size in the FW image.

We have filed bugs specifically for 2.0 and 2.1 releases. If there is a driving bug that requires us to create a patch release we will consider fixing this bug in those patch releases.

This issue will be used to track the fix going into Caliptra-SS's "main" branch for all future releases.

2.0: #979
2.1: #980
