Why does the 0xA0 vendor command to load the firmware into FX2LP return failure on certain firmware?
The FX2LP bootloader supports the 0xA0 vendor command to load the firmware into the internal RAM. When using a custom application (other than Cypress’ USB Control Center) to load firmware into the FX2LP, the code range of FX2LP firmware should be set to 0x80 – 0x0FFF. This corresponds to the internal RAM range of FX2LP. Any code range beyond this would point to external RAM and 0xA0 vendor command cannot be used to load the firmware.
