The problem was in toolchain file. It had CMAKE_C_FLAGS set to some value and CMAKE_C_FLAGS_INIT didn't work. After changing  CMAKE_C_FLAGS to

string(APPEND CMAKE_C_FLAGS_INIT " -DARM64=1 ...")

all works fine.

Hi Kareem,
could you please point me to the missing option? I have an error with unresolved "_ToTraditionalEnc" referenced from      wolfSSL_d2i_PKCS8PrivateKey_bio in libwolfssl.a(ssl.o).
I created options.h like this

#include <IDE/XCODE/user_settings.h>
#include <wolfssl/wolfcrypt/settings.h>

And put following defines at the top of user_settings.h

#define WOLFSSL_LIBWEBSOCKETS
#define HAVE_EX_DATA
#define OPENSSL_NO_EC
#define OPENSSL_ALL
#define WOLFSSL_EITHER_SIDE
#define WC_RSA_NO_PADDING
#define WC_RSA_PSS
#define WOLFSSL_PSS_LONG_SALT
#define OPENSSL_EXTRA
#define HAVE_ALPN
#define HAVE_PKCS8

I put HAVE_ALPN to fix unresolved _wolfSSL_get0_alpn_selected.
To fix unresolved ToTraditionalEnc I put HAVE_PKCS8, but it didn't help. May be it gets overridden somewhere else...

Thanks,
Roman

Hi David,
could you please point me to the proper pinout? I found one for TPM module on asus site, but it differs from pinout I have in asus b550m-a mainboard manual.

Thanks,
Roman

Hi Jeff,
thanks for the fix!
Roman

On oscilloscope I don't see any signal on MISO line, only on MOSI. Sending init command via spidev_test shows no answer as well:

pi@raspberrypi:~/spi_test/new $ ./spidev_test -D /dev/spidev0.0 -v -s43000000 -p "\x80\xd4\x00\x00\x00"
spi mode: 0x4
bits per word: 8
max speed: 43000000 Hz (43000 kHz)
TX | 80 D4 00 00 00 __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __  |.....|
RX | 00 00 00 00 00 __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __  |.....|

I tested this TPM on ASUS board and BIOS could detect it, so it should be OK. Some connection should be a problem. I tried to set almost all undocumented pins high, but it didn't help. In attachment I push photo of setup with connections as you described.

Hi Kareem,
thanks, I'll give it a try.
I built it this way (with lws), but could not test yet if it really works:

./configure --host=arm-apple-darwin --disable-shared --prefix=${PWD}/inst --enable-opensslextra --enable-libwebsockets --enable-certgen --enable-certreq --enable-certext --enable-pkcs7 --enable-cryptocb --enable-aescfb --enable-alpn
make CC="$(xcrun --sdk iphoneos -f clang) -isysroot $(xcrun --sdk iphoneos --show-sdk-path) -arch arm64 -miphoneos-version-min=12.5"
make install

Hi David,
thank you for your response. I connected RST with VCC to put it high. Or should I put pull-up resistor instead? I also put 10k resistor between VCC and CS0. But still no answer from device. I attached image with connections. May be I have to try with another Raspi ...
