Error with CONFIG_CMD_ZYNQ_AES / CONFIG_CMD_ZYNQ_RSA configs #6

Hi all,

we are heavily using your Mercury ZX5 boards with your bsd-xilinx (version 1.8.2) u-boot (V2018.01). If used with default Mercury config for QSPI boot (even with some minor modifications), it works well for us. Now, we would like to add cryptography capability and encrypt our bitstream. According to Xilinx documentation, we need for this zynqaes command which is enabled with u-boot CONFIG_CMD_ZYNQ_AES define. However, if we add this define and the others below to allow u-boot to compile, this u-boot binary hangs up during boot and we cannot even reach u-boot shell.

CONFIG_SHA256=y CONFIG_CMD_MD5SUM=y CONFIG_CMD_ZYNQ_RSA=y CONFIG_CMD_ZYNQ_AES=y

The only message which appears on the UART port is:

initcall sequence 0407db50 failed at call 040013cc (err=-12) ### ERROR ### Please RESET the board ###

Can you advice us what is wrong or how to debug this issue? Have you tried cryptography functions with this your u-boot fork?

Thank you in advance, Michael

Hi Michael,

At the moment I cannot say what is causing this issue. As a workaround i would suggest to use the master branch which is based on xilinx-v2019.1.
