| 21 | # This board support package works with several different versions of |
---|
[396286a] | 22 | # MC68360 systems. See the conditional-compile tests in startup/init68360.c |

---|
[f8f370b6] | 25 | # Decisions made at compile time include: |
---|
| 26 | # - If the CPU is a member of the 68040 family, the BSP is |
---|
| 27 | # compiled for a generic 68040/68360 system as described |
---|
[396286a] | 28 | # in Chapter 9 of the MC68360 User's Manual. This version |
---|
| 29 | # can be used with the Arnewsh SBC360 card. |
---|
[f8f370b6] | 30 | # - If the preprocessor symbol M68360_ATLAS_HSB is defined, |
---|
| 31 | # the BSP is compiled for an Atlas HSB card. |
---|
| 32 | # - Otherwise, the BSP is compiled for a generic 68360 system |
---|
[396286a] | 33 | # as described in Chapter 9 of the MC68360 User's Manual. This |

[e2d79559] | 35 | # |
---|
[f8f370b6] | 36 | # Decisions to be made a link-edit time are: |
---|
[1f0f3e35] | 37 | # - The size of the memory allocator heap. The default value is |
---|
[28e7d7fa] | 38 | # 64 kbytes. If the network package is used the heap |
---|
[1f0f3e35] | 39 | # should be at least 256 kbytes. If your network is large, or |
---|
| 40 | # busy, the heap should be even larger. |
---|
| 41 | # To choose a heap size of 256 kbytes, |

| 282 | described in chapter 9 of the Motorola MC68360 Quad Integrated Communication |

[e2d79559] | 283 | Processor Users' Manual. The salient features of this hardware are: |
---|
[457b6ae] | 284 | |
---|
| 285 | 25 MHz external clock |
---|
| 286 | DRAM address multiplexing provided by 68360 |

| 287 | 8-bit 180nsec PROM to CS0* |
---|
| 288 | 4 MBytes of 60 nsec parity DRAM (1Mx36) to RAS1*/CAS1* |

---|
[457b6ae] | 291 | |

| 303 | Interrupt Notes |
---|
| 304 | =============== |
---|
| 305 | ckinit.c: |
---|
| 306 | Occasional network lockups have been noted when the PIT has a higher |
---|
| 307 | interrupt request level than the CPM. The SCC1 bit in the CISR is set |
---|
| 308 | even though the SCC1 interrupt handler is not active. This blocks |
---|
| 309 | interrupts from SCC1 (and all other CPM sources) and locks up the |
---|
| 310 | system. It has not been determined whether the error is within the |
---|
| 311 | 68360 or in the RTEMS interrupt support assembler code. The solution, |
---|
| 312 | for now, is to set both PIT and CPM interrupt request levels to the same |
---|
| 313 | value (4). |
---|
| 314 | |
