hi,

非常感谢你的回答,我还有2个问题想咨询下:

1.SBAF是出厂自带的,那么S32K324芯片出厂自带的SBAF版本号是多少呢?如果我直接使用0.2.40.0版本的HSE固件会造成和出厂SBAF版本不兼容吗?

2.如果我将SBAF版本更新到0.0.15.0版本,那么0.0.40.0的HSE固件版本会和0.0.15.0版本的SBAF不兼容吗?

Best Regards,
Wiho

1. SBAF出厂自带的,根据出厂日期不同默认的SBAF版本不同。你也可以通过0x4039C020查看SBAF版本号。请看RM758223-HSE-B Firmware Reference Manual - V2.3(2.3).pdf的 Table 140. Secure BAF version number HSE GPR (0x4039C020)。 至于SBAF和HSE FW版本兼容性,请看RM758223-HSE-B Firmware Reference Manual - V2.3(2.3).pdf的14.7 HSE Firmware and Secure BAF release version compatibility章节。

2. SBAF版本0.0.15.0和HSE FW版本0.2.40.0是兼容的。

您好,我想问一下如果HSE firmware一直就固定在一个版本上,但是SBAF随着芯片出厂日期一直更新最新版本的话,会不会有可能出现SBAF和一直固定的这个HSE firmware不兼容的情况出现?
