工具与软件:
尊敬的 TI 支持部门:
我目前在使用 OTP Keywriter (PSDK RTOS J721S2 08.04)时遇到问题。 + OTP_KEYWRITE_ADD_ON_j721s2_08_04_00_02):
对开发过程进行编程、测试和验证 不带扩展名的 OTP 数据 、OTP Keywriter 会成功:
OTP Keywriter Version: 02.00.00.00 (Nov 21 2024 - 09:45:21) OTP Keywriter ver: 8.4.6-v08.04_keywriter (Jolly J Key programming sequence initialted Taking OTP certificate from 0x41c73004 Debug response: 0x0 Key programming sequence completed
对开发过程进行编程、测试和验证 扩展 OTP 数据 、OTP Keywriter 出现故障 KEYWR_ERR_INTERAL_OP (调试响应0x20):
OTP Keywriter Version: 02.00.00.00 (Nov 21 2024 - 09:45:21) OTP Keywriter ver: 8.4.6-v08.04_keywriter (Jolly J Key programming sequence initialted Taking OTP certificate from 0x41c73004 Sciclient_otpProcessKeyCfg returns: -1 Debug response: 0x20 Key programming sequence completed
生成
带有扩展 OTP 数据:
./gen_keywr_cert.sh -s keys/smpk.pem --smek keys/smek.key -b keys/bmpk.pem --bmek keys/bmek.key -t ti_fek_public.pem -a keys/aes256.key --ext-otp ext_otp_data.bin --ext-otp-indx 0 --ext-otp-size 1024
外部 OTP 数据:
$ xxd ext_otp_data.bin 00000000: 0000 ccdd 0000 0000 0000 0000 0000 0000 ................ 00000010: 0000 0000 0000 0000 0000 0000 0000 0000 ................ 00000020: 0000 0000 0000 0000 0000 0000 0000 0000 ................ 00000030: 0000 0000 0000 0000 0000 0000 0000 0000 ................ 00000040: 0000 0000 0000 0000 0000 0000 0000 0000 ................ 00000050: 0000 0000 0000 0000 0000 0000 0000 0000 ................ 00000060: 0000 0000 0000 0000 0000 0000 0000 0000 ................ 00000070: 0000 0000 0000 0000 0000 0000 0000 0000 ................
不带扩展 OTP 数据:
./gen_keywr_cert.sh -s keys/smpk.pem --smek keys/smek.key -b keys/bmpk.pem --bmek keys/bmek.key -t ti_fek_public.pem -a keys/aes256.key
您能告诉我将 ext_otp 插入 x509扩展字段时 OTP Keywriter 过程可能会出现什么错误吗?
此致、
