You create some Cipher/MessageDigest instance in your applet. These instances need COR/COD memory space for each update() and the doFinal() method. The use of these RAM spaces are not visiable directly from source code.
The WORK_BUFF_1 is not used, i comment it and the applet installed succeeded.

@JavaCardOS, please look into implementing SCP03 into JC30M48CR whenever possible as SCP02 has been found to be weak while SCP03 has been proven to be robust.

Thank you very much for your feedback.
In fact, we have already implementing SCP03 in JC30M48CR
and it's a customization feature for JC30M48CR
. In current market, SCP02 is more popular than SCP03, so we set SCP02 as default setting. If the customers need SCP03 on JC30M48CR
, we can customize the cards according to their requirement.
