System halt when using STM32CryptographicV3.0.0_CM4_KEIL_otslsm1elfspf.lib on STM32F429IGT

[YChen.51]

Hi all

I used STM32CryptographicV3.0.0_CM4_KEIL_otslsm1elfspf on STM32F429 for ECC encrypt and decrypt. But after use several time library function(likes ECCinitEC, SHA256_Append, etc), the system was halted.

If I used AES encrypt and decrypt functions, all ok.

Can anyone help me?

PS: I used the example code from STM32CubeExpansion_Crypto_V3.1.0\Fw_Crypto\STM32F4\Projects\STM32F401RE-Nucleo\ECC\KeyGen_Sign_Verif
