Regarding the HARD-RESET for CCG3PA Analyzer log

[NoAr_1540581]

Please find attached.
CC communication log (CY4500) on a board equipped with iPad Pro 2018 and CCG3PA.Since the CCG3PA side operates only as a Power Source (5V 3A), the ipadPro 2018 should charge.But, It is not charged and VBUS output stops.

Q1) HARD-RESET occurs in several places in the log. Could you please tel lme the cause of this message?
Q2) Also, are there any places on the log that seem to be performing strange operations other than HARD-RESET?

(In Japanease)

iPadPro2018とCCG3PAが搭載された基板でのCC通信ログ（CY4500）となります。

CCG3PA側は、Power Source（５V　3A)のみとして動作しますので、ipadPro2018は充電さるはずですが、

充電されず、且つVBUS出力が停止します。

Q1)　ログに　HARD-RESETが数か所現れますが、このメッセージが表示される原因として考えられる事はありますでしょうか？

Q2)　又、ログ上　HARD－RESET以外でおかしな動作をしていると思われる個所がありますでしょうか？

Hi Arai,

It seems you are not testing Cypress latest firmware (build#1882) on CCG3PA and the iPad pro 2018 is not latest IOS version (higher 12.1.1). You please kindly check it.

Best Regards,

Lisa

Hello Lisa san

Regarding the CCG3PA firmware, they are using customize firmware with customer's prototype board, not using SDK sample firmware.

Q1) From the above, is it ok to think that it is related with only iPad pro 2018 version?

Q2) Please tell me about the lof contents that I attached before.Why "HARD_RESET" will be occured? If there are some issue, please tell us me the point for  CY4500 log?
