i.MX RT685 fails with "CMSIS-Pack device MIMXRT685SFVKB has no identifiable boot memory [cmsis_pack]" because of algorithm for memory range

[ErichStyger]

pyOCD fails to flash/program the i.MX RT685 using the 18.0.0 pack. The main error message is

CMSIS-Pack device MIMXRT685SFVKB has no identifiable boot memory [cmsis_pack]

The issue seens to be caused by using a memory range twice in the PDSC:

<algorithm name="devices/MIMXRT685S/arm/MIMXRT6XX_EVK_FLEXSPI.FLM" start="0x08000000" size="0x04000000" RAMstart="0x1001c000" RAMsize="0x00001000" default="1"/>
        <algorithm name="devices/MIMXRT685S/arm/MIMXRT6XX_EVK_FLEXSPI_S.FLM" start="0x18000000" size="0x04000000" RAMstart="0x1001c000" RAMsize="0x00001000" default="1"/>
        <algorithm name="devices/MIMXRT685S/arm/MIMXRT6XX_FLEXSPI_B_SFDP_QSPI.FLM" start="0xF8000000" size="0x04000000" RAMstart="0x1001c000" RAMsize="0x00001000" default="0"/>
        <algorithm name="devices/MIMXRT685S/arm/MIMXRT6XX_FLEXSPI_B_SFDP_QSPI_S.FLM" start="0x18000000" size="0x04000000" RAMstart="0x1001c000" RAMsize="0x00001000" default="0"/>

So the workaround is to remove the two last lines above, to have only one algorithm per memory range.

I'm not an expert in PDSC files, but it seems that other tools do accept the above? pyOCD should accept it too?
