LCP1519 can not go ISP ( use API -Chip_IAP_ReinvokeISP())

[yansinli]

QIZ1 : LCP1519 can not  go ISP ( use API -Chip_IAP_ReinvokeISP())

        Chip_IAP_ReinvokeISP (BOOT_CAN);  // In LPC1519 can not go ISP ,but LPC 1517 is OK

QIZ2 :  Different CPU frequency， need other setting? (1517 run 64M Hz / 1519 run 72M Hz)

---------------------------------------------------------------------------------

Note : Check if go to ISP  by  read device ID .  in LPC1517 is OK(see picture yellow). InLPC1519 is not ok.

Hi yansi lee,

   1. LCP1519 can not  go ISP ( use API -Chip_IAP_ReinvokeISP())

         When calling the reinvoke API, do you disable irq? If yes, please call go to ISP IAP code before calling __disable_irq().

        Please try it again.

    2. Different CPU frequency， need other setting? (1517 run 64M Hz / 1519 run 72M Hz)

      The LPC15xx operate at CPU frequencies of up to 72 MHz. So 72Mhz works OK, you don't need other settings.

Have a great day,
Kerry
