PSoC® Creator™ 1.0 Service Pack 2 is a mandatory update to version 1.0 Production and Service Pack 1. Service Pack 2 is a complete superset of Service Pack 1.
All versions of PSoC3 Application Note projects and code example designed with PSoC Creator 1.0, with device silicon as ‘Production / ES3’ when opened in PSoC Creator Service Pack 2 will generate an error message. This is to enforce the user to update to v2.21 of CY_BOOT.
When a project originally designed using PSoC® Creator™ 1.0 is opened with PSoC® Creator™ 1.0 Service Pack 2 (SP2), the following screen would appear prompting the user for an upgrade. Select the “Yes” option here. This would update the CY_BOOT to v2.21.
